You can only flat tow some Range Rover models—and even then it’s for very short distances at very low speeds. No Range Rover should be flat towed for more than 30 miles, and the speed should be no higher than 30 mph. Unfortunately, this means that flat towing a Range Rover behind an RV or motorhome on a trip is not an option.
You probably can’t safely use a tow dolly for your Range Rover either. If you need to take it on your trip with you, your best bet is to get a car trailer.
