I got our rv from a guy towing a mini. He bought and I now am using a falcon all terrain tow system. He also had a SMI brake system installed. When we bought the unit he gave us all that he had. The tow bar works well I did have to buy the base plate for our car and the SMI installs in the engine compartment and is virtually invisible. We had only 1 problem with it on our trip. The did not install a charge line when they installed the lighting kit, so it took a friend and I about 2 hrs to get it set up. Dont ever try to find anything in Van Horne Tx, just not a lot there to work with!
BTW he said he was told by the cooper folks NOT to tow his mini, but he did and I guess it worked out for him, he kept the car as a DD for the wife.
