Many years ago we witnessed the house portion of a TT lift up and peel off its frame while it was going down the road. We had to slam on the brakes to keep from hitting it as it slid down the highway on its side. I stopped to help and the driver said he had been driving on some rough logging roads. His two dogs were inside but were in crates and they seemed to be OK.
I could actually see where the bolts that held the box to the frame had pulled out and left neat holes. The only funny part was I saw a mouse stick its head out one of the holes and dart back in.
So I would be very careful and avoid any surface that makes the trailer twist too much.
