I have given the issue of adding a bike rack on the back of my
Scamp a lot of thought. I had all the material gathered up and was all set to fabricate a receiver hitch when I changed directions. With the hitch I would have still had to buy a bike rack, which I do not currently have. For the same amount of trouble (and far less $$$$) I could just build the whole rack from scratch. My current plan is to come up off the bumper on each side of the spare tire with an upright. I will tie the uprights together above the tire with a cross-over piece. Rods will stick back from the cross-over piece to hold the bikes. I also plan on adding a tab in the middle sticking up to mount a nice bright LED tail
light on since bikes tend to obscure the trailer mounted
lights. Anywho, I think for me this is a better approach and no more trouble than mounting the hitch.
