Dinghy Towing

This is not a law, but a statement. "If you wish to tow a vehicle behind your RV, you need to consider whether or not your motor home can handle the extra weight under all conditions (i.e., climbing steep hills or mountains). Your vehicle must have sufficient power to climb grades without holding up traffic and its braking power must be sufficient to stop the combined weight of the RV plus the car and/or tow dolly effectively. RV chassis manufacturers provide limits on the gross combined weight of the RV plus car"
