Years ago I helped a friend move from Nebraska to Texas. He had a small trailer he didn't want so I took it.The trailer had 2 attach points on the bumper and sat on 2 steerable wheels. It was narrow and short, maybe 4 X 5 ft long. I hooked it up to my 67 Chysler for several dump runs and it was great. No problem backing up as there is no swivel and you remembered the extra length behind you, and no problem with swinging too wide on turns as it was narrow enough to stay within the vehicles swing. Do they still make these? I would think they would be great for towing motorcycles behind RV's. There is very little weight on the hitch or bumper.
Edit: Swivelwheel.com has a great setup for motor homes
