Very interesting! I see potential there. It would make a GREAT extra room for the Mother-in-law! Attach to the bumper of your camper and away you go!
Would also work good for a couple kids that don't want to share space with Mom and Dad inside the main camper either.
I like the hitch idea. It could be attached to a 5er, MH, trailer, back of a truck, small car, anything that has a receiver hitch.
The only problem I saw was, it covers the license plate of the vehicle. That would have to be worked out.
When they say, "call for more information" and won't put the price on the web site, you know is going to cost a fortune that a normal personal would never pay!
Still, it's an interesting concept and I see potential for this catching on and becoming popular.
