There are many options when it comes to towing a vehicle. These include using a trailer, tow bar or tow dolly. A tow dolly is a two-wheel trailer that keeps only the drive wheels of a vehicle off the ground during the tow. While this type of trailer is easier to store and cheaper to buy or rent than other options, using a tow dolly to tow vehicles has its pitfalls.
Tow dollies can’t carry as much weight as other car trailers. Tow dollies rented through the moving trailer company U-Haul cannot carry front-wheel drive or all-wheel drive cars that exceed 3,450 lbs. Rear-wheel drive cars cannot weigh more than 3,900 lbs. when using a U-Haul tow dolly. This eliminates many sport utility vehicles, trucks and older steel-frame cars from being able to be towed with a car dolly.
