Fellow RVers,

I tow a 5er with a Dodge V10 dully.  I have been looking for an auxiliary gas tank to put in the bed of the truck that will set level with the sides of the bed.  Almost all the tanks I see are diesel or cost in excess of 1000 dollars.  Does anyone have any suggestions on where to get a gas aux tank a little cheaper?

Thanks,


Mike

How about these types of tanks? www.tank-depot.com
Make absolutely certain it is classified as a "gas" tank to make it legal to fill at the pump - i.e. milk jugs are not fuel tanks.

Mike--- I work for a natural gas company and we have safety courses constantly. I don't want to cause a controversy but I would not consider any kind of plastic container to hold gasoline under any circumstances if you are planning to haul this in any vehicle. I haven't researched portable gas tanks but I know there are numerous portable gas tanks that are rated for gasoline that are metal and are safe for storage and transportation. These gas storage tanks are more expensive but are well worth the extra money. I would not jeopardise the safety of my family just to save a few dollars. JMHO.

Hubby ordered a tank from Northern Tools I think it was around $500 or so for a diesel tank.

don't want to be the naysayer, but why do you think you need an auxilliary tank? Most trucks come with a tank sufficient for 3-400 miles travel. We've been fulltime for about 2 1/2 years now and have never seriously been close to running out of fuel, and that includes our recent jaunt to Alaska through some pretty remote areas. Why carry all that additional weight? JMHO. Fred

At one time husband was talking of the need to an auxiliary tank. I think I finally convinced him it is a waste of money. As Fred said, why would we want to haul around that additional weight. I can not imagine we would be any place that we could not find fuel and we fill up once we get down to a little under 1/2 tank anyway.

I have 2 tanks on my F550 and when I find fuel at a lower price I can add $150 to the tanks and save a few $$. (except when I was in Needles Ca a couple days ago and paid $5.89). I did not really need it but was a easy in and easy out. Maybe you can find one that mounts under the bed. ?

Thanks for all of your inputs.  With a gas engine I only get about 6 to 7 miles per gallon towing the 5er.  With a 35 gallon tank I usually get about 200 miles before I'm looking for a fill-up.  I just felt that with another 25 or 30 gallons of gas I could get to where I'm headed without an extra stop.

You've given me something to think about.

Thanks again,

Mike

Fred...Like Mike stated at 200 miles per tank, I can see the advantage of an extra tank. My 08 F-450 diesel only gets 200 miles on a tank and a few times I have been so close to out. I will continue to make do, but the auxillary tank has an appeal.

Must be a Ford thing I have an 05 F250 with the 5.4 and I only get 200 miles out of a tank. Most unhandy!

igotjam- what are you pulling? What size tank do you have now? I asking because within the next two years I will be getting a newer 5th wheel and I was thinking about moving up to a F450, but if you are only getting 200 miles per tank I may reconsider. I get 10-11 mpg with my 2001 F350 now with a 38 gal fuel tank. I would hate to give up that kind of mpg to go to a newer truck.

We're pulling about 16,200 with our 06 F350 diesel and experience about the same as you, 9 - 10mpg on a 39 gallon tank.

Considerably more range than the 200 miles he's getting. Even coming through the most remote areas of northern Canada and the Yukon we were almost always able to refill before we were much below the halfway mark.

I have learned from this forum the best way to travel is about 200 to 250 miles at one time. If this is the case you need to plan your stops using that milage and then you don't have to worry about extra tanks and extra diesel. Is someone in a hurry here??? Take your time and smell the roses along the way and stop trying to push that rig 300 to 400 miles in one trip...you might miss something along the way. Speedy

Ken & Sarah....not sure of tank size (o8 F-450 only has one size available) but I tow a 20,000 lb fifth wheel (DRV Elite Suite). The F-450 has 4.88 gears (required to legally tow 20,000 lbs) and I get about 6.5 mpg towing. If you tow less than 20,000 lb you could get the 4.30 gears and get better mileage.
