The Lexa Country Coach I had before my Liberty, I purchased from a guy who had a blue ox tow bar for the Coach. He woulldn't sale me the Tow bar, who knows why. Anyway, I'm thinking there's probably a lot of that kind of stuff on e-bay. If I were to tow, I would want something simple , and not heavy.
I rent cars as needed since we usually travel to a destination rather than touring.
