Dinghy towing, 4 wheels down and flat towing are different ways to say that you are towing an automobile behind a motor home or RV. Some people call the towed vehicle a toad. No matter how you say it, in order to tow a vehicle behind a motorhome or RV legally in any State or Province you must have a base plate bracket installed on the "toad" to connect a tow bar to, you need a tow bar and safety cables, a supplemental braking system, a break away system and a light kit to display stop, turn and running lights on the toad
