throb I will again recommend the heavy duty, non swiveling wheels be mounted on your hitch. I have skids on my 33ft class A, they were badly worn and worn more than half way through. Visiting my family in Federal way WA, very hilly near the bay, I tore gouge in ft of pavement in ft of their home. Got a set of the Castor's that when mounted are just about 1/2 inch below my skids, problem solved, my visit to them in august this year No drag just rolled over. My drop hitch for the toad also cleared. I believe I paid about $55.00 for them. If I ever sell this beast I will in bolt them and use them on the next MH I get. Best luck enjoy your travels I love the Washington Islands.
