In Europe and the UK the smart is towed behind motor home and it is NOT necessary to use a dolly OR a trailer.
Here's a functional link to that FAQ page:Smart FAQssmart USA plans to develop a tow-bar for the smart fortwo that can attach to the front of the vehicle to allow for flat towing. In addition, the car can be towed on a flat bed.
This seems to me a clear implication that flat towing the smart is OK.
Hello whalewatcher. I would like to know how your roadmaster is attached to the front end of your smart car?? And does the installation look clean?Smart cars can be towed 4 down as I did 300miles over the weekend with a new car picked up 12/17 and fitted with roadmaster system. Follow rules in manual brakes- parking and regular on, move gear to neutral .turn key as far left as possible, leave it in slot. release brakes, turn off non tow switch on dash - see manua, l close door and go. mileage does not register and MH did not notice it was pulling such a light vehicle.
