We're in Elkhart with our rig at mor/RYDE .. getting the 8K (I think) IS with Disc Brakes. We're getting all their stuff including the relatively new "step above" steps. Additionally, we're getting 17.5" high spec aluminum wheels and Goodyear G114 H rated tires. Oh ... all that stuff is free but the Tee Shirt costs $9K ... they do provide a "free" lunch.
Pretty good outfit with exceptional people and top notch products. Looking forward to being put back together and being back on the road.

You better be getting 8K axles! - along with a full alignment. I like the "steps above" product. Simple but a very nice implementation that seem to work quite well. Trust they will continue to treat you well as they have us and the installation will be to your liking. Say Hi to Rob for us please and you might ask the receptionist to track down Gary Wheeler to take you on a plant tour if he's in town. Lots of interesting CAD/CAM cutting equipment making lots of "stuff."

FWIW, that's what we do. I let MORryde do a yearly re-pack and inspection. One can do this themselves but if there is anything wrong the tech will find it and many times it's repaired under warranty. As long as I see no abnormal wear on the tires I typically don't do a re-alignment unless Sergio sees something that might need attention.
If one travels, IS or not, these suspension systems receive a lot of wear and tear on the bad roads including interstates and a yearly inspection is not overkill IMO. Just good PM. And is normally the case at MORryde, an appointment is really an appointment for service. Not an appointment to "get in line" for service as with many places. We've been delayed once or twice but it wasn't their fault. People before us had major problems due to rig overloading and the anticipated work was much more extensive to fix frames, etc. once the cracks were discovered. Happens more often then one might expect - hidden on-going issues from overloading that are discovered at inspection time.

I misspoke. It's actually the translator that takes the Ford electric brake controller signal and coverts it to hydraulic pressure (via a pump) to the disc brakes. Not sure what the proper name of it is, but I'd call it an actuator.

We got our rig finished today and are now camped in the Elkhart Campgrounds. You will be impressed with MORryde. They are impressive as a Company, how they treat their employees and how they behave toward the community. Ask about the little house on the property, that just about tells you all you need to know about the company. OBTW, they make awesome products.

Good to hear all went well as expected. Sometimes a hiccup but in the RV world MORryde and their products are about as good as it gets, IMO. Always stood behind their work for us and they do things on-time and as promised.

Many companies have trouble with that "do the right thing" part. Normally it goes off the rails when the bottom line gets too important, shareholders often drive that. As long as mor/Ryde remains a privately held company, they can preserve the values the owners chose. In this case, it was "do the right thing" ... it's what makes mor/Ryde exceptional.

I have a question for those with experience with adding the morRyde IS. I know it adds weight ... you can just look at what goes on and what comes off to see this. I also know that the IS is unsprung weight (meaning that the frame doesn't have to "carry" that weight, but the GVW of the trailer has changed ... haven't gotten to a scale yet so I don't really "know" how much it's changed. I was weighed by morRyde after (but surprisingly, not before) the installation wheel by wheel, but the trailer wasn't level and the total weight is unusable (as a wheel by wheel) because the front wheels were very heavy compared to the rear, so not usable other than for total weight. Based on my last total weight and the new one from morRyde ... it looks like the total weight increased by 960 lbs. It's reasonable to assume that each axle gained 1/2 of that so each "axle" went up 480 lbs. Does this jive with what you saw when the IS was added?
Thanks for any input

That sounds really high, Ron. Sergio told us the 7K MOR/ryde system should add about 300 lbs. total to the unsprung weight. We found that it was closer to 425 total per the CAT scales.

Thanks Rob ... we're going to be on the move soon and I will hit a scale ... I really wish morRyde had done a proper wheel by wheel before and after ... but it is what it is. My technician (Allen) said he thought it was "about 400 lbs" ... which jives with your experience.

MORryde would have done a wheel-by-wheel before and after if you had requested it. But as you were going up to 8K what it was at 7K was pretty academic to them. If you had said you wanted to stay at 7K then they might have suggested a weighing to make sure 7K was acceptable. That was a discussion we had when we had the first trailer converted to an IS. It was a 7K trailer. Wasn't sure if I needed 8K. So Sergio weighted it. Some discussion with the shop manager was going on with me RE: 7K vs. 8K, etc. Sergio leaned over to Linda and said: "8K." Linda leaned over to me, said "Sergio says 8K." I said to the shop guy, "8K." Not trying to make light of it but they would have done that had it been necessary or had you requested a 7K weighing, IMO.
As to the 480 / per axle total - yea that doesn't sound too far off to me. Recall you went from 7K to 8K axles. The IS 8K is bigger (steel sizes) then a 7K IS and much bigger than traditional springs and axles. Also you added disc brakes and "H" tires. The "H" tires are heavier then "G" in themselves. It all adds up. Recall those two big boxed cross members between the actual IS "axles" actually reinforce the frame. Lots of steel that, as you correctly noted, is carrying its own weight along with the "H" tires, etc. None of that is on the frame. Truck must pull that weight, but the trailer does not carry it.
My experience and opinion FWIW

Well that throws a kink into our upgrade planning. Our currrent top pick 5er weighs 13425 as delivered with a GVWR of 16850. So, with the IS upgrade to 8k and H tires we were looking at 18850 GVWR. leaving 5425lbs for everything else. Now if 960 lbs is lost to the upgrade... we're down to 4465 available. We've calculated 1700 lbs approx for solar, batteries, second ac, genny, W&D, Awnings and other optional gear. That leaves 2765 lbs for everything else.... clothing & linens, kitchen gear, food, water (80 gal), toys and other gear, tools and maintenance items, cleaning equipment and supplies, pet items, campsite items... have we forgotten anything? Is 2765 lbs enough?

Bill,
I did request it before ... when I asked the answer from the tech was "I forgot". I requested an "after" weigh and the rig was 3" low in the front (which I noticed after it was pulled out of the bay) and the weights reflect it ... very heavy on the front two axles and light on the two rear ones. Pretty sure the total weight is reliable so that's what I'm going on. You are correct that there is a LOT of metal in those assemblies ... impressive. They also welded a 4" and a 1" box riser tubes to make everything turn out right height wise. This adds strength at the frame to IS attachment area, so pleased about that. Rob told me that the rubber springs will "settle" about 1/2" after they've been in service for a little while. All that to say I'm OK with how level everything is, just need to get it weighed wheel by wheel so I'll know what tire pressures to run.

Brian,
It's not a straight 1:1 for the added added weight from the suspension upgrade. The weight from the I.S. is on the suspension itself - not on the frame. In fact, the sub-frame that MOR/ryde fabricates for mounting of the I.S. helps distribute the load on the frame better than the original hangers and attachment points... a LOT better.
We aren't the heaviest packers around - but we're not the lightest, either. We have right at 2,000 lbs. of personal stuff on board: four seasons of clothing, two computers, a guitar, food, usually about 100 lbs. of soft drinks and distilled water, etc., etc., etc.
It's just my personal opinion, but from your numbers, I don't think you have anything to worry about.

Brian,
I agree with Rob. The GVWR that the manufacturer puts out assumes all weight added will be carried by the frame. In this case none of the additional weight will be carried by the frame. It doesn't affect your CCC at all, but it will show up on the scale, and the truck will have to pull it. Another of the many nuances of GVWRs and how they work in the full timers world.

I am trying to understand this myself (I consider myself a pre-newbie since I have not bought an RV yet). My understanding of GVWR is that regardless of what modifications you do to your rig, including increasing the axle weight rating, you can't increase your trailer's GVWR - only the manufacturer can do that - in your case it it would still be 16850. So if you could carry 3425 lbs before the modification, than that is how much your trailer is rated to carry after in total weight (but now the axle sides would be better equipped to handle a heavier load on the sides.) And your truck needs to be able to handle the extra towing weight.
RonC said
08:59 PM Aug 12, 2017
John ... you are correct, the GVWR is unchanged. The CCC the manufacturer allows assumes that the trailer will carry all the added weight on the frame. In the case of the MORRyde IS, all added weight is below the frame, so it doesn't encroach on the CCC, but does increase the GVW. Hope this explains it ... if not, I'm not sure I can offer more.

Then the tech didn't do everything you requested, but that doesn't impact accuracy of the installation. Those number wouldn't change what he did but would have been nice to know just to know them. Totally agree on the wheel by wheel. Based on experience, until I weighted the rig, I'd run 100 which covers the 4K max hub rating. But that's just my opinion. Here are the Goodyear published pressure chart numbers for the G114 tire so you can make a choice. I would not run the max of 125 psi regardless. Again, my opinion. 125 psi is for 4,806 lbs of load. 'Bit much for our rigs, and then some.

Brian: What Rob said. Do I think 2,765 is enough? Probably. And maybe, after careful consideration and consultation you only need 7K axles, which weigh less, due to the base weight of the rig. Wait till you get to the service bay to discuss this with good numbers. There is an evaluation to be done. But there is no way the trailer isn't safer with the axle and tire upgrades. Try not to mix apples and oranges numbers wise. The 7K axles have 8K hubs and then "H" tires as well for safety. I agree with Rob and as he said and IMO, "I don't think you have anything to worry about."

And your truck needs to be able to handle the extra towing weight.
You're correct about the GVWR... I misspoke... with the upgrade the GVWR "techniquely" stays at 16850. I have read several letters from the NHTSA to various inquirers on this subject and and they don't specifically prohibit such modifications to carry additional weight but such modifications to carry additional weight beyond the MFRs stated GVWR should consider the capabilities of the axles, tires and rims, brakes, frame, hitch pinbox and any other components that may affect load ratings. It's all somewhat confusing and a lot of what seems to be legalese shirking of culpability in the event of an accident. In the end it boils down to buyer beware... like any other product. Given Mor/Ryde's reputation and track record thus far, we feel safe. I'd certainly keep any paperwork from Mor/Ryde regarding the installed upgrades handy for any LEO or other bureaucrat that wanted to verify our specs.
I also believe that there is a "legal" path for re-certifying modified trailers but I am not versed in that subject.
I was comfortable with the modifications we desire to install with our expected loadout... until I read in this thread (and assumed incorrectly) that the IS, brake and tire/rim upgrade added 960lbs of weight that then subtracted from CCC. From that I made the error thinking that we might now be overweight because I failed to account for that extra 960 pounds. I correctly added it to the total trailer weight. If it turns out that we can't carry more than 3425lbs all in with stronger axles, tires, rims and brakes, then we may have to do some re-evaluating of our assumptions. I'm in contact with an owner of a similar unmodified unit but I can't make head or tails of his numbers which don't seem to gibe with published numbers from the mfr. I have started a dialog with the Mfr.
Lastly, given the above numbers, we are fully comfortable that our future intended TV is well within it's capabilites with room to spare for the intended application.
I'm certain if I get any of this incorrectly, the pros round these parts will jump in to keep me on the straight and narrow. Like you, I want to understand this stuff as best as I can.

John,
You want MOR/ryde to match the suspension system (7K vs. 8K, springs, etc.) to the actual wheel-by-wheel weights on your rig. I'll coin a phrase here and say that there is such a thing as being "over-suspended." That is to say, too much spring and tire capacity for the weight on the suspension system. This results in the springs not flexing (suspension doesn't travel up and down) and the tires being "hard" and not making full contact with the road resulting in a much harsher ride for the rig and possible metal fatigue and stress damage to the frame from repeated hard hits.

Might not be enough. Our NH UVW is 18,420. The only upgrade we've added since is the solar panels and controller which are 8x 30 or so pounds and another say 10 for the controller, maybe 400 total. Trailer weight last spring was 23,320 with 100 gallons of fresh and empty waste tanks. Would have been about 22,500 without water so our stuff is right about 4,000.

I appreciate the information from all in this thread.

John,
You want MOR/ryde to match the suspension system (7K vs. 8K, springs, etc.) to the actual wheel-by-wheel weights on your rig. I'll coin a phrase here and say that there is such a thing as being "over-suspended." That is to say, too much spring and tire capacity for the weight on the suspension system. This results in the springs not flexing (suspension doesn't travel up and down) and the tires being "hard" and not making full contact with the road resulting in a much harsher ride for the rig and possible metal fatigue and stress damage to the frame from repeated hard hits.
Rob
Thanks, Rob. Your point makes sense. The listed GVWR of the unit that is in the lead for our choice so far is 16,500. I will have to see what the delivered specs are when we get it. Besides the excellent advice from this forum, I will be relying on MORryde's expertise once they have the RV in hand and are able to evaluate it and provide their recommendation. In the meantime I will plan on that possibility and in the end if it doesn't make sense to do it, then that will be one less outlay of money.

Seems to have gone well ... items not properly secured in the fridge were still there when we stopped, so that potential "whoops" was avoided. Couldn't weigh it due to ENTIRE trip being first on Indiana tollway, then Ohio Tollway. Currently at a very nice little military park (Camp Perry) in Ohio. We'll stay a week then move on. Hope to weigh it on the next leg.

Rob told me that the rubber springs will "settle" about 1/2" after they've been in service for a little while.

Then the tech didn't do everything you requested, but that doesn't impact accuracy of the installation. Those number wouldn't change what he did but would have been nice to know just to know them. Totally agree on the wheel by wheel. Based on experience, until I weighted the rig, I'd run 100 which covers the 4K max hub rating. But that's just my opinion. Here are the Goodyear published pressure chart numbers for the G114 tire so you can make a choice. I would not run the max of 125 psi regardless. Again, my opinion. 125 psi is for 4,806 lbs of load.

I weighed my Cedar Creek on a CAT scale on my way to MORryde, it had 9,875lbs on the 5K axels, I wanted to get the 8K MORryde IS but Rob convinced me that would be over kill resulting in a rough ride. He went with the 7K and I am very pleased with the ride. I never feel a bump when you go over it. I think the two axels being independent is the main reason for the Great ride. the added weight of the MORryde is Unsprung weight.

Your welcome, happy to help as I can. The info by Cummins I do agree with as per the GY tech. Use the heaviest wheel weight, go by the charts and then add 5 psi. And just to be clear for anyone reading along for info, whatever the heaviest wheel is, that is he wheel that sets the air pressure for all tires regardless of the lighter weight on the other tires. This must be done cold. Meaning not after moving the rig, before. Hence the practical need for a 150 psi rated compressor. Saw them at Lowe's today BTW for $129.00. Porter Cable version. Works good for the purpose.
Don't be surprised if all you need is 95 psi. And don't be overly concerned about being low or high at this point. It does matter, but not nearly as much with these commercial grade tires for a short time.
BTW, next time your going over a set of railroad tracks see if you don't notice the trailer "echoing" the truck as it goes over the tracks. First time I pulled the exact same trailer with the IS after upfit that is what I noticed - that I did not feel the trailer's echo bouncing after the truck when over the tracks.
Safe travels,
Bill

Danny, your comments are right on. You sure can have too much suspension. Usually a 7K upgrade to 8K is OK on almost any rig. But from 5K or 6K OEM, must be careful. They can change out the rubber "springs" for different stiffness depending on the load as well. But all of mine, each time, have been the correct selection from the git-go.

We had a great visit with MorRyde. In at 6am out by 8am. Everything looked good
5 of the 6 wheels were close one was way off, we are now tracking straight and should have no trailer worries off to Kanas to see the New Horizon wizard for some minor warranty items..
We do seem to be having a truck issue however so we are dropping the truck off at the Ram dealer to get checked out. We seem to be low on coolent but see no leaks and not running hot. It has to be going somewhere, hoping it is not a leaking intercooler for the turbo.
We are in Chatham Ill for the next 12 days so what ever it is hope to get it taken care of while hear.
RonC said
03:11 PM Aug 19, 2017
Interesting that our "destinations" seem to include maintenance (MorRYDE, manufacturer, etc) ... just part of the lifestyle I guess.
Sorry to hear about the truck ... you are right that in the absence of leaks, the coolant is migrating somewhere. Are you "making" oil? Diesels can and do blow head gaskets ... this can manifest itself as an increase in oil level and dilute the oil and cause other problems if allowed to go unaddressed. One of the shade tree ways to check for water in the oil is to take your oil dipstick and put a drop of your oil on a HOT exhaunt manifold. If it bubbles that indicates water in the oil, it should just smolder and smoke as the oil burns off. Bubbling is caused by any water present boiling off.

I'd say you're only a couple of hours from the eclipse totality path on Monday, but the weather appears as if its not going to cooperate in southern IL, SE MO area. You might catch a gap between the clouds that forecast for that afternoon. Still... moonshadow during midday-ish and the sudden temp drop off will be freaky enough if you've never seen one before.

Front axle now 6,920 (LT side 3,560, RT side 3,360). Rear axle now 6,640 (LT side 3,420, RT side 3,220).

We're in Elkhart with our rig at mor/RYDE .. getting the 8K (I think) IS with Disc Brakes. We're getting all their stuff including the relatively new "step above" steps. Additionally, we're getting 17.5" high spec aluminum wheels and Goodyear G114 H rated tires. Oh ... all that stuff is free but the Tee Shirt costs $9K ... they do provide a "free" lunch.
Pretty good outfit with exceptional people and top notch products. Looking forward to being put back together and being back on the road.

You better be getting 8K axles! - along with a full alignment. I like the "steps above" product. Simple but a very nice implementation that seem to work quite well. Trust they will continue to treat you well as they have us and the installation will be to your liking. Say Hi to Rob for us please and you might ask the receptionist to track down Gary Wheeler to take you on a plant tour if he's in town. Lots of interesting CAD/CAM cutting equipment making lots of "stuff."
Bill
FWIW, that's what we do. I let MORryde do a yearly re-pack and inspection. One can do this themselves but if there is anything wrong the tech will find it and many times it's repaired under warranty. As long as I see no abnormal wear on the tires I typically don't do a re-alignment unless Sergio sees something that might need attention.
If one travels, IS or not, these suspension systems receive a lot of wear and tear on the bad roads including interstates and a yearly inspection is not overkill IMO. Just good PM. And is normally the case at MORryde, an appointment is really an appointment for service. Not an appointment to "get in line" for service as with many places. We've been delayed once or twice but it wasn't their fault. People before us had major problems due to rig overloading and the anticipated work was much more extensive to fix frames, etc. once the cracks were discovered. Happens more often then one might expect - hidden on-going issues from overloading that are discovered at inspection time.
Bill
I misspoke. It's actually the translator that takes the Ford electric brake controller signal and coverts it to hydraulic pressure (via a pump) to the disc brakes. Not sure what the proper name of it is, but I'd call it an actuator.

I have a question for those with experience with adding the morRyde IS. I know it adds weight ... you can just look at what goes on and what comes off to see this. I also know that the IS is unsprung weight (meaning that the frame doesn't have to "carry" that weight, but the GVW of the trailer has changed ... haven't gotten to a scale yet so I don't really "know" how much it's changed. I was weighed by morRyde after (but surprisingly, not before) the installation wheel by wheel, but the trailer wasn't level and the total weight is unusable (as a wheel by wheel) because the front wheels were very heavy compared to the rear, so not usable other than for total weight. Based on my last total weight and the new one from morRyde ... it looks like the total weight increased by 960 lbs. It's reasonable to assume that each axle gained 1/2 of that so each "axle" went up 480 lbs. Does this jive with what you saw when the IS was added?
Thanks for any input

That sounds really high, Ron. Sergio told us the 7K MOR/ryde system should add about 300 lbs. total to the unsprung weight. We found that it was closer to 425 total per the CAT scales.
Rob
---------------------------------------------------------------------
MORryde would have done a wheel-by-wheel before and after if you had requested it. But as you were going up to 8K what it was at 7K was pretty academic to them. If you had said you wanted to stay at 7K then they might have suggested a weighing to make sure 7K was acceptable. That was a discussion we had when we had the first trailer converted to an IS. It was a 7K trailer. Wasn't sure if I needed 8K. So Sergio weighted it. Some discussion with the shop manager was going on with me RE: 7K vs. 8K, etc. Sergio leaned over to Linda and said: "8K." Linda leaned over to me, said "Sergio says 8K." I said to the shop guy, "8K." Not trying to make light of it but they would have done that had it been necessary or had you requested a 7K weighing, IMO.
As to the 480 / per axle total - yea that doesn't sound too far off to me. Recall you went from 7K to 8K axles. The IS 8K is bigger (steel sizes) then a 7K IS and much bigger than traditional springs and axles. Also you added disc brakes and "H" tires. The "H" tires are heavier then "G" in themselves. It all adds up. Recall those two big boxed cross members between the actual IS "axles" actually reinforce the frame. Lots of steel that, as you correctly noted, is carrying its own weight along with the "H" tires, etc. None of that is on the frame. Truck must pull that weight, but the trailer does not carry it.
My experience and opinion FWIW
Well that throws a kink into our upgrade planning. Our currrent top pick 5er weighs 13425 as delivered with a GVWR of 16850. So, with the IS upgrade to 8k and H tires we were looking at 18850 GVWR. leaving 5425lbs for everything else. Now if 960 lbs is lost to the upgrade... we're down to 4465 available. We've calculated 1700 lbs approx for solar, batteries, second ac, genny, W&D, Awnings and other optional gear. That leaves 2765 lbs for everything else.... clothing & linens, kitchen gear, food, water (80 gal), toys and other gear, tools and maintenance items, cleaning equipment and supplies, pet items, campsite items... have we forgotten anything? Is 2765 lbs enough?
Brian

-- Edited by RonC on Saturday 12th of August 2017 03:41:18 PM
Brian,
It's not a straight 1:1 for the added added weight from the suspension upgrade. The weight from the I.S. is on the suspension itself - not on the frame. In fact, the sub-frame that MOR/ryde fabricates for mounting of the I.S. helps distribute the load on the frame better than the original hangers and attachment points... a LOT better.
We aren't the heaviest packers around - but we're not the lightest, either. We have right at 2,000 lbs. of personal stuff on board: four seasons of clothing, two computers, a guitar, food, usually about 100 lbs. of soft drinks and distilled water, etc., etc., etc.
It's just my personal opinion, but from your numbers, I don't think you have anything to worry about.
Rob
Thanks Rob, hadn't considered the weigh of the IS and tire upgrade in that light.... Just saw absolute numbers and became concerned. Hopefully that leaves more room for solar and batteries.. LOL.
Brian
Brian,
I agree with Rob. The GVWR that the manufacturer puts out assumes all weight added will be carried by the frame. In this case none of the additional weight will be carried by the frame. It doesn't affect your CCC at all, but it will show up on the scale, and the truck will have to pull it. Another of the many nuances of GVWRs and how they work in the full timers world.
-- Edited by RonC on Saturday 12th of August 2017 07:22:17 PM
-- Edited by RonC on Monday 14th of August 2017 07:18:06 AM
I am trying to understand this myself (I consider myself a pre-newbie since I have not bought an RV yet). My understanding of GVWR is that regardless of what modifications you do to your rig, including increasing the axle weight rating, you can't increase your trailer's GVWR - only the manufacturer can do that - in your case it it would still be 16850. So if you could carry 3425 lbs before the modification, than that is how much your trailer is rated to carry after in total weight (but now the axle sides would be better equipped to handle a heavier load on the sides.) And your truck needs to be able to handle the extra towing weight.
Then the tech didn't do everything you requested, but that doesn't impact accuracy of the installation. Those number wouldn't change what he did but would have been nice to know just to know them. Totally agree on the wheel by wheel. Based on experience, until I weighted the rig, I'd run 100 which covers the 4K max hub rating. But that's just my opinion. Here are the Goodyear published pressure chart numbers for the G114 tire so you can make a choice. I would not run the max of 125 psi regardless. Again, my opinion. 125 psi is for 4,806 lbs of load. 'Bit much for our rigs, and then some.
110 psi = 4,340 lbs 105 psi = 4,180 lbs 100 psi = 4,020 lbs 95 psi = 3,860 lbs 90 psi = 3,695 lbs.
Brian: What Rob said. Do I think 2,765 is enough? Probably. And maybe, after careful consideration and consultation you only need 7K axles, which weigh less, due to the base weight of the rig. Wait till you get to the service bay to discuss this with good numbers. There is an evaluation to be done. But there is no way the trailer isn't safer with the axle and tire upgrades. Try not to mix apples and oranges numbers wise. The 7K axles have 8K hubs and then "H" tires as well for safety. I agree with Rob and as he said and IMO, "I don't think you have anything to worry about."
You're correct about the GVWR... I misspoke... with the upgrade the GVWR "techniquely" stays at 16850. I have read several letters from the NHTSA to various inquirers on this subject and and they don't specifically prohibit such modifications to carry additional weight but such modifications to carry additional weight beyond the MFRs stated GVWR should consider the capabilities of the axles, tires and rims, brakes, frame, hitch pinbox and any other components that may affect load ratings. It's all somewhat confusing and a lot of what seems to be legalese shirking of culpability in the event of an accident. In the end it boils down to buyer beware... like any other product. Given Mor/Ryde's reputation and track record thus far, we feel safe. I'd certainly keep any paperwork from Mor/Ryde regarding the installed upgrades handy for any LEO or other bureaucrat that wanted to verify our specs.
I also believe that there is a "legal" path for re-certifying modified trailers but I am not versed in that subject.
I was comfortable with the modifications we desire to install with our expected loadout... until I read in this thread (and assumed incorrectly) that the IS, brake and tire/rim upgrade added 960lbs of weight that then subtracted from CCC. From that I made the error thinking that we might now be overweight because I failed to account for that extra 960 pounds. I correctly added it to the total trailer weight. If it turns out that we can't carry more than 3425lbs all in with stronger axles, tires, rims and brakes, then we may have to do some re-evaluating of our assumptions. I'm in contact with an owner of a similar unmodified unit but I can't make head or tails of his numbers which don't seem to gibe with published numbers from the mfr. I have started a dialog with the Mfr.
Lastly, given the above numbers, we are fully comfortable that our future intended TV is well within it's capabilites with room to spare for the intended application.
I'm certain if I get any of this incorrectly, the pros round these parts will jump in to keep me on the straight and narrow. Like you, I want to understand this stuff as best as I can.

John,
You want MOR/ryde to match the suspension system (7K vs. 8K, springs, etc.) to the actual wheel-by-wheel weights on your rig. I'll coin a phrase here and say that there is such a thing as being "over-suspended." That is to say, too much spring and tire capacity for the weight on the suspension system. This results in the springs not flexing (suspension doesn't travel up and down) and the tires being "hard" and not making full contact with the road resulting in a much harsher ride for the rig and possible metal fatigue and stress damage to the frame from repeated hard hits.
Rob
Might not be enough. Our NH UVW is 18,420. The only upgrade we've added since is the solar panels and controller which are 8x 30 or so pounds and another say 10 for the controller, maybe 400 total. Trailer weight last spring was 23,320 with 100 gallons of fresh and empty waste tanks. Would have been about 22,500 without water so our stuff is right about 4,000.
That's what I'm doing ... 100 psi per tire, which I suspect will be what I wind up with. Not freaked out about the wheel by wheel weights, but very curious. Thanks, Bill, for your mentorship!

Thanks, Rob. Your point makes sense. The listed GVWR of the unit that is in the lead for our choice so far is 16,500. I will have to see what the delivered specs are when we get it. Besides the excellent advice from this forum, I will be relying on MORryde's expertise once they have the RV in hand and are able to evaluate it and provide their recommendation. In the meantime I will plan on that possibility and in the end if it doesn't make sense to do it, then that will be one less outlay of money.
Seems to have gone well ... items not properly secured in the fridge were still there when we stopped, so that potential "whoops" was avoided. Couldn't weigh it due to ENTIRE trip being first on Indiana tollway, then Ohio Tollway. Currently at a very nice little military park (Camp Perry) in Ohio. We'll stay a week then move on. Hope to weigh it on the next leg.

Per GY Tech Support. Weigh each tire if possible or weigh each axle. Use weight/inflation chart and add 5psi. I have used this method for years and have gotten excellent tread wear and ride quality.
I weighed my Cedar Creek on a CAT scale on my way to MORryde, it had 9,875lbs on the 5K axels, I wanted to get the 8K MORryde IS but Rob convinced me that would be over kill resulting in a rough ride. He went with the 7K and I am very pleased with the ride. I never feel a bump when you go over it. I think the two axels being independent is the main reason for the Great ride. the added weight of the MORryde is Unsprung weight.

Your welcome, happy to help as I can. The info by Cummins I do agree with as per the GY tech. Use the heaviest wheel weight, go by the charts and then add 5 psi. And just to be clear for anyone reading along for info, whatever the heaviest wheel is, that is he wheel that sets the air pressure for all tires regardless of the lighter weight on the other tires. This must be done cold. Meaning not after moving the rig, before. Hence the practical need for a 150 psi rated compressor. Saw them at Lowe's today BTW for $129.00. Porter Cable version. Works good for the purpose.
Don't be surprised if all you need is 95 psi. And don't be overly concerned about being low or high at this point. It does matter, but not nearly as much with these commercial grade tires for a short time.
BTW, next time your going over a set of railroad tracks see if you don't notice the trailer "echoing" the truck as it goes over the tracks. First time I pulled the exact same trailer with the IS after upfit that is what I noticed - that I did not feel the trailer's echo bouncing after the truck when over the tracks.
Safe travels,

Danny, your comments are right on. You sure can have too much suspension. Usually a 7K upgrade to 8K is OK on almost any rig. But from 5K or 6K OEM, must be careful. They can change out the rubber "springs" for different stiffness depending on the load as well. But all of mine, each time, have been the correct selection from the git-go.
I guess NH did a better job of sizing your springs…M/R swapped out our rubber springs for the next stiffness up on our first visit.
5 of the 6 wheels were close one was way off, we are now tracking straight and should have no trailer worries off to Kanas to see the New Horizon wizard for some minor warranty items..
We do seem to be having a truck issue however so we are dropping the truck off at the Ram dealer to get checked out. We seem to be low on coolent but see no leaks and not running hot. It has to be going somewhere, hoping it is not a leaking intercooler for the turbo.
We are in Chatham Ill for the next 12 days so what ever it is hope to get it taken care of while hear.
Interesting that our "destinations" seem to include maintenance (MorRYDE, manufacturer, etc) ... just part of the lifestyle I guess.
Sorry to hear about the truck ... you are right that in the absence of leaks, the coolant is migrating somewhere. Are you "making" oil? Diesels can and do blow head gaskets ... this can manifest itself as an increase in oil level and dilute the oil and cause other problems if allowed to go unaddressed. One of the shade tree ways to check for water in the oil is to take your oil dipstick and put a drop of your oil on a HOT exhaunt manifold. If it bubbles that indicates water in the oil, it should just smolder and smoke as the oil burns off. Bubbling is caused by any water present boiling off.

Took it to a Ram dealer today, they will look at it Monday morning. What ever it is ,it should be under warranty. But hope it is something simple so that time down is not a issue. So glad we have the extra car, so that will not slow us down while we are here in the Springfield Ill. Area. Looks like there is a lot to do hear.
I'd say you're only a couple of hours from the eclipse totality path on Monday, but the weather appears as if its not going to cooperate in southern IL, SE MO area. You might catch a gap between the clouds that forecast for that afternoon. Still... moonshadow during midday-ish and the sudden temp drop off will be freaky enough if you've never seen one before. FWIW

Got on a CAT scale today. My rig's actual (unsprung) weight went up 880 lbs, so about 440 net per axle (8K, disc brakes and 17.5 wheels and Goodyear G114 H rated tires).
Front axle now 6,920 (LT side 3,560, RT side 3,360).
Rear axle now 6,640 (LT side 3,420, RT side 3,220).
Currently running 100 psi cold on all positions.
