Sold the old axle, tires, wheels, springs, and associated hardware. Used some of the money to purchase the Joy Rider shock system and installed it on the camper. Also purchased a receiver hitch for the rear of the camper. In a few weeks I'll take it and the camper by a welding shop and have a cross member installed so I can bolt the hitch to it. This will serve as a mounting point for my Yakima Fullswing 4 bike carrier. The intent is to be able to set up the camper with bikes mounted on it.
