When I tried to rent a tow dolly today, I was informed that U-Haul no longer rents anything to owners of Ford Explorers. So, if you are planning to tow a Corvair and have one of those turn-over prone vehicles - isn't this beautiful irony? - be sure to pick up your trailer or dolly with something else :-). Also wise not to identify the towed vehicle as a Corvair..... Grant
