Buying a tow dolly can cost  $1,000-$4,500, depending on towing capacity, size, quality of materials and other options. For example, the Roadmaster RM3477 Tow Dolly with built-in electric brakes sells for $1,600 -$2,000, and can tow a vehicle weighing up to 4,250 pounds.
With a tow dolly, the drive wheels of the car are the ones that belong on the trailer. For older, rear-wheel drive cars, the vehicle is driven backwards onto the tow dolly so that the rear drive wheels are off the ground.
