Replacing plastic undercarriage sheeting...

Thanks for the detailed explanation. I have one that I know of hanging loose. Kicker is, It is not under the wall framing. Instead, Right infront of it. I don't know if the rest are like that though. I had two places that had to have floor repair and I don't think we ran the new sheets under the walls. I can always cut some pieces to fit under and screw them down. I have no way of lifting the body off the chassis. Would using leveling shims work if I used them as I move along? My plans are to strip this unit down to the framing and rebuild it. Starting from the bottom and working up. New flooring, wiring, plumbing, remodeling, installing a washer/dryer unit, dishwasher, new siding,insulation, etc... But I need to first make sure everything is secured to the chassis. The tongue needs re-welded because it is literally higher at the ball joint than where the chassis begins. I'm thinking if I can remove all the body bolts, I could shim the body high enough to slide a corriboard sheet through. Or am I wrong? I remember looking at your project a while back. You have some balls to take on a project like that. Seems like a lot of work and money for something that is waaaaay to far gone.
