I use one to carry my bikes. I bought a bike attachment for mine that the front wheels ride in, think old school bike racks, so I don't have to remove the front wheel. It is made for 3 bikes but I can only carry 2 because the oversized spare tire on my Jeep blocks off one of the loops. I can send you a cell phone pic if you pm me your email address. The other downfall you didn't mention that I have with mine is I have to take the bikes off if I want to get in the back. But other than that it comes in handy for camping and hauling stuff that won't fit inside the cabin.
