Traveling without a spare tire

I'd also recommend getting a spare. Of the 4 Class C's I've had/have, 2 had spares mounted on relatively simple brackets under the MH, with the spare mounted between the frame rails. Removing/replacing them wasn't particularly easy, but the vehicles had spare tires. My Coachmen 220RK had a spare tire mounted on a bracket on the rear wall. The wall was reinforced to carry the considerable weight of the spare tire. My 31K came without a spare. I bought one and I put it in the large outside rear storage compartment, against the rear bedroom interior wall. I've thought about making or having a frame mounted carrier installed, but since I don't need the room that the spare takes up, I haven't bothered.
