Forgot to mention: We put a spare tire bike rack on our camper (DO NOT TRY THIS!) and the tire, rack, and bikes fell off. Fortunately, this happened as we backed into a campsite, so no real damage to anyone or anything. The spare tire is put on with screws instead of bolts. We were going to beef it up with some bar stock and bolts, but we can't get to the spot on the inside. So we plan to buy a hitch bike rack that has a ball to tow the camper with.
