A motor home is much easier to back into a site than any trailer even if it's bigger. The vehicles which can be 4-wheel towed with an auto trans. is shrinking fast. Even some manuals can't be. Trailer Life puts out a towing guide I think annually and you can start there. But the final authority is the vehicles owner's manual, under a "towing behind a motor home" section. based on my son having a dolly then 4-wheel towing, I would not recommend a dolly. However, none of it is easy. Lots of little things can effect the ease of hooking up the towed car and the auxillary brake hook-up is a multi-step process.
