The best vehicles to flat tow behind an RV include the Jeep Wrangler, the 4x4 Chevrolet Silverado 1500 with an automatic transmission, the Nissan 370Z and the Ford Fusion Energi, according to Edmunds. Any vehicle can technically be towed behind an RV, but flat towing means all of the vehicle's tires are on the ground.
The Jeep Wrangler is probably by far the most popular and best vehicle to flat tow behind an RV. It has a simple transmission system, and it is a rugged vehicle that often appeals to those using RVs to facilitate outdoor activities.
Trailering a vehicle behind an RV is unpopular and impractical. Buying and licensing a trailer is expensive and a hassle, as is moving the vehicle on and off the trailer. Most people with RVs flat tow vehicles for those reasons. Flat towing consists of attaching a tow bar to the vehicle and letting it roll behind the RV with all four tires on the ground.
Flat towing a vehicle in the past was easy due to the simplicity of transmission systems. The electronic systems in current vehicles present a higher degree of difficulty. For example, no Toyota-made vehicle with an automatic transmission can be flat towed behind an RV as of 2013 due to the lack of transmission lubrication.
