First thing to do , is get the Trailer tow weight rating for the coach.
It'll probably be 5,000lbs. Then you have a base line, weight, of vehicles to choose from, that fit your every day driving needs.
Many 4 wheel drive vehicles, with a neutral in the transfer case can be flat towed without expensive modifications.
With the tow bar system, base plates, transmission fluid pump ( optional depending on vehicle) and towed vehicle, brake system. Budget $5,000 to get the vehicle ready to tow. You can save about $ 1,300 or so if the pump system is not required.
And , I see Bob, types faster than I do; everyone types faster than I do.
