The only thing I will add is that, If you can, rent (or borrow) something like what you might buy. That may change your might very fast.
We have a tiny antique class A. We love it and I carry bicycles most of the time rather then drag the towed. A towed is a pain, but if you coach is too large to be maneuvered everywhere you might want to be, then you kind of need some way to get there. A friend never drags anything, but they do make plans to rent a car when they are traveling to someplace that they will want be able to get around the town.
