Thanks for sharing this! Just a couple days ago I mentioned to my wife I thought it would be fun to get a trailer frame, like a double axle utility trailer with electric brakes, or something like that, get it registered as a utility trailer and then build a house on it. Why utility trailer? Because in Indiana pop-up are considered utility trailers and not RV's. Anyway, it would be an interesting and fun project. I've got the carpentry skills to do this. So, yea, this is a great post!
More than likely, I would think this lady would use the "home" similar to a park model. She could be planning on parking it on a lake or who knows where. On wheels, it can always be moved if you don't like the neighborhood any more! And no one says you have to tow it at 70 miles an hour down the interstate either. A s..l..o..w... tow and it can be moved easy enough, even if the roof has household asphalt shingles!
