Adding adjustable ride height to older Fontaine RGN

We have an '02 55-ton Fontaine RGN, 3 axle +1 (flip down). This trailer obviously has some heavy duty airbags due to its weight carrying capability but along with that comes a nominal ride height that is higher than we would prefer! I was trying to find someone that has done or knows someone that has successfully fabricated the ability to adjust the ride height on these older trailers? It only has one leveling valve on the middle axle of the three, so I figured it may be easier than you think to accomplish. It would be nice to have the ability to drop the ride height down a couple of inches at most which would help tremendously with the height of most loads we haul with it.

 

I agree with all that you suggest, but probably wasn’t clear on exactly what I have in mind. I want to fabricate a mechanism that allows us to select multiple different ride height detents. We also have a ‘17 Jet ag trailer that allows this with a handle that moves the leveling valve and allows you to select 5 different ride height detents.

 

Yeah, I have seen online that the new trailers have it. I’m planning on trying to go look in person at how they do it to get some ideas. Just looking for advice if anyone has done it.

 

I thought that as well, but dealer said nothing like that exists!
