I recently bought a 2001 Trail Lite 7212. I think there is a leak in the fresh water system (tank or piping) and I need to get into the underbelly. The camper has a series of panels that I am guessing are a tongue and groove design. Has anyone had to access this area on your camper? It looks like they are held on by screws through a trim piece on the side, but there also appears to be an adhesive to seal the sides. This adhesive looks like some type of double stick foam tape. Can anyone help give me some guidance on how difficult it is to get into this area?
