I have used Allen brand racks for over 40 yrs. Started with trunk/hatchback mounted racks and found them to be economical and reliable but you would have to expect some minor wear on the bike frame paint. A couple of years ago a friend of mine gave me a hitch mounted Allen rack which was brand new. I invested in a hitch for my Rav4 and had to buy an extension to have the rack clear the exterior mounted spare tire. It works great and no damage at all to my bikes. I have a 3 bike rack but never put more than two on in order to minimize the potential for damage. Here is the 3 bike model
