I don't have your coach but on my Sprinter, I installed Sumos on the front and rear at the same time. It stopped the terrible side to side motion when we drove into/out of driveways. It also eliminated the side sway when passing or being passed by large trucks. The Sumos filled the gap between the frame and axle where the factory bumps stops had a large gap(space) between the frame and axle.
