I have the Watts Model H560 and it works quite well. Gives very good volume at all pressures.

We went with the Watts IR56 based on this statement on the website you linked:
"Similar to the H560, but an improved model is the Watts IR56. This unit has a little better flow than the H560, and it gave us 3 to 3.5 gpm in our test. It also seems to be more immune to clogging than the H560, so over time, it will require a little less maintenance."
We got it with the 2" diameter gauge. It is adjustable up to 60 psi. There are other adjustables on the site that go up to 125 psi. I'm just not very trusting of devices, so I wanted our maximum psi to be 60 just in case the thing malfunctioned. Just a little of my own paranoia.
We should have gotten this thing a long time ago. Of course it doesn't help as much when the overall pressure in a campground is low, but if the pressure is good our water flow is now so much better. Can't believe it took us over a year to buy one.

Were did you get your Watts Regulator? Can you get them at Lowes or Home Depot?

We got ours through the RV Water Filter Store as was linked in the first post for this topic. I wasn't able to find them at the Lowe's or Home Depot websites. You can go through www.watts.com but I really like the RV Water Filter Store website and they have taken care of us when we have ordered through them.

Will this new pressure regulator help with the trickle effect I get at some RV parks. I hate getting in the shower and the water is dripping out. I have taken the regulator off and we have plenty of water, but then I am worried that we will bust a line.

Assuming the plumbing in your RV is okay, there are a couple of things that could be affecting the water flow. The regulator is one of them. The problem with the Marshall Brass regulator sold at most RV parts places is that the internal diameter of the device is too small. When a faucet is opened the regulator restricts the volume of water causing the pressure on the RV side to drop. The pressure regulators described in the other comments will resolve that issue. If you are in a campground where the water is supplied by a well then the pressure will decrease as water is used from the pressure tank on the campground side. Usually these pumps are turned off and on by a pressure switch on the system so that the pressure in the tank is held relatively constant but if the pressure sensor is bad or improperly adjusted the pressure on the entire campground system can vary a great deal. There is nothing the pressure regulator you use can do about that. That problem will stay at the campground and not follow you. If the problem follows you it is most likely your regulator restricting the volume of water.

Thanks I need to get the new regulator

Also note that in most RVs you can leave the water pump on while hooked to city water. If the pressure is too low, which can happen many places without a pressure regulator, the pump will come on and increase the pressure. Just watch the water tank meter and fill it back up as needed. We have been in campgrounds where we had to fill the water tank once a week due to low water pressure. If you do not boondock you can replace your water pump with the fancy $160 Shurflo that will give you great pressure. Boondockers avoid them since it makes it harder to conserve water when the pump pushes it out so fast.
Looking at this website, http://www.rvwaterfilterstore.com/PressureRegulators.htm I'm wondering which regulator is recommended by those in the know.
