My son, who has no towing experience, is planning a move from Iowa to Ohio. He plans to rent a moving truck (U-Haul, Penske, etc), and is wondering how to get his std transmission Camry moved. As I see it, his options are: tow bar, tow dolly, or trailer. All would be using the rental truck to tow. What advice do y'all have for him?

Thanks,
Marty
