A tow dolly is a type of trailer designed to transport a vehicle behind another vehicle, typically a motorhome or pickup truck. It supports the front wheels of the towed vehicle while allowing the rear wheels to remain on the ground. This setup is useful for towing cars without needing a full trailer. Tow dollies are often equipped with adjustable ramps and safety straps to secure the towed vehicle. They are popular among RV enthusiasts and those who need to move vehicles over long distances. Using a tow dolly can simplify the towing process and reduce wear on the towed vehicle.
