In May 2007, we bought a Scion xB manual to tow. Since it was a new car, base plates from Blue Ox and Roadmaster were not available. Since we had good experience and support from Blue Ox and had a Blue Ox tow bar, we wanted to stay with them. By late August they still had not developed a base plate. So, we bought a base plate from Roadmaster and had it installed at the factory. (We were getting ready to leave our work camper job and relocate. So we needed a new base plate ASAP). I watched the install at the factory and noticed that they removed the entire styrofoam backing behind the bumper and did NOT replace it. They replaced the OEM metal bracket with their own and mounted the new base plate to it. The rest of the install was standard Roadmaster parts. But, there are so many interlocking pieces! IMHO, the bracket, which is flush-mounted, needs to be moved forward an inch. It its present position, it is difficult to get the locking pin in and out. And, I can not add a lock instead of a pin. I should have found a way to wait for Blue Ox. Both companies do support their product.
