It's leaf springs on all 4 corners not coils but they have the blocks for the rear. Coils would be a better ride tho. It's fun but a rough rideHe also stays on pavement most of the time. He sold the frig. and battery for $250 (cost him nearly $700) later and bought a Casita trailer. Widh I'd watched him sooner than I did, That was a good buy. Hope you figure a way to make your work..
Do they make spacers for your model Ramcharger ? In the old days when springs (coil springs) were a little saggy they sold some wedges that you could place between the coils that would bring back the stock height. I think they still sell them. The last time I had this problem was on the rear of my car. I bought air shocks and just added air that raised it up enough for tire clearance. That may be a solution for you as well. Just put the same amount of air pressure on each side to raise it equally. They may make an air bag for coil springs that would be better.
