I recently bought a travel trailer and needed something to carry two bikes. I liked the idea of this model because it uses rear bumper space already used by the spare tire. One can't beat the price from Overstock.com!Overall the unit installs easily, although it's helpful to have a friend to hold it steady while tightening the bolts. I used it last weekend and everything stayed where it was supposed to be and stayed tight. If there was one negative (hence three stars for durability) it would be the J hooks that keep the bike in place. The four J hooks are way too long. It takes five minutes to unscrew it so the top portion of the hook can clear the bike. The rubber coating the top of the J hook also peels off and/or tends to work its way forward leading to the rubber getting bent up and ripping.I know I can get the Dremel out and shorten the end of the J hooks so this is no big deal.Overall, knowing what I know about this bike rack after using it, I would buy it again.
