Thinking of just putting the spare in the bed of the truck.
Anyone else mount a bike rack there or how do you carry your bikes?
Only need to carry two at the most.
Definately stay away from mounting a bike rack on the rear bumper. Most racks are made to be used with a receiver type installation. There are "bolt on" receiver attachments for the TT bumper. Son-in-law did it and was lucky he got home with the bikes still on the TT. The top of the bumper was cracked along the welds that attached it to the frame. According to a welder friend of ours, when asked if the bumper could be reinforced to handle the weight and stress, his response was that the "sewer hose tube (not really a bumper at all) was made of such thin metal that it would tear away from any welded support." The welds wouldn't break the metal would just sheer due to the twisting stress of the bikes and rack bouncing up and down. We removed our bumper mount receiver and invested in a real frame mounted receiver ($350) for the bike rack. So did the SIL but it cost him another $150 to repair his bumper. It was a tough pill to swallow, $350 to carry the bikes but we sure didn't want to be the cause of some freeway disaster if it all came loose because we were trying to save a few bucks.
