The Timbren # TMBRSP35A replacement bump stops are a fit for your motorhome, but the Timbren product can provide a pretty stiff ride.
I'd recommend the SuperSprings Solo replacement bump stops, part # SSR-338-54. The SuperSprings Solor will offer up to 1400 lbs of support but are constructed of a more pliable material than the Timbrens, and would offer a more comfortable ride.
