Currently we tow a 2015 Ford Escape with a Dolly. Thinking of getting a new vehicle, possbly a 4X4. Since we also have a VW Bettle that can be towed with the Dolly, I don't want to have to go out a purchase a complete set up for flat towing. My question is, can a vehicle that can be flat towed also be towed with a Dolly?
