I have a 2008 Smart Passion, and a 38' Holiday Rambler Navigator. I have pulled my Smart over 20,000 miles with no problems whatsoever. My car was the model car for Blue Ox to make a base plate back in Feb of 2008. I hook up the tow bar and the lights cable, put the car in neutral, turn off the key ( it only goes part way), and pull it away. At first, when I went around a tight turn, the steering on the Smart would hunt back and forth lock to lock, a very unsettling feeling, even for a big heavy bus like mine. So, I put a bungee cord through the steering wheel and attached it on each side to the seat rack, and presto, problem solved.
