While we haven't dug into the Toyolet yet, we spent months gutting a shuttle bus - redoing the entire subfloor frame. What a mess. I was thankful we had the use of a shop to work on it. It has an entirely different structure than a camper. It's amazing a camper stays upright with how lightweight they are built. I know the bottom edge of the outside of the Toyolet is rotted, can't wait.. lol..
