I've been carrying a 125cc scooter on a rack for a few years now, but age and the need for more comfortable, and dry, travel has cemented the idea of towing a car in the future. Rang about 4 of the main suppliers but only one responded and didn't answer my questions. My camper is a 6 metre 2.3hp Ducato weighing in at 3500Kg gross. We already have a Nissan Micra diesel car and I would like to tow it. But will it be ok? Also not sure about the difference between the over-run system or the more expensive one. (not sure what it's called) I understand they now have to be EU 2014 compliant, operating all four wheel brakes - that doesn't sound like the over-run system used on caravans. Any advice on tow-cars would be greatly appreciated. Sunty.
