I have a ceiling panel in the master bedroom of our Sundance XLT fifth wheel that is warping and separating from the ceiling. It is the first panel above the top shelf of the headboard. At first I thought the trim piece joining the paneling of the headboard and the ceiling had come loose but further inspection revealed that a small section of the ceiling panel itself was warped on the left side. When you push it back up against the substrate it doesn't feel tacky at all. Does anyone know what holds those panels up? I can't find any evidence of fasteners. The roof seam outside where it joins the front cap is pristine. I can't find any evidence of leakage. Looks like a two hour trip to the dealer for me. I suppose I should be glad it's under warranty. <sigh>
