Lots of variables. But the easiest I have found is a small vehicle, 4 down, tow bar. Something like a standard shift Totyota Yaris. You won't even feel it back there. Some people like an easy to operate tow dolly with a small car.
With a Yaris for instance and a tow dolly, you could probably even get away with just putting the lights on it. Brakes etc., blah because it's such a light car behind the mass of the RV.
But anyway, to your question there are tons of variables. What kind of weight cans yours tow?
