Thought I would start a Thread under this heading for future research. Jon and others have entered important information under Ah, Nice Coach.

It is my understanding many XLII"s have had an adhesion problem for years before it is discovered. In fact, the problem is usually uncovered by Prevost Facilities rather than owners. The panels start leaking water behind the adhesion and runs out the bottom side. Sometimes water leaks or stains are discovered inside the Coach as evidence of the compromise. Although the Techs are willing to talk about the procedures and repairs, I think they have been instructed to not divulge information.
