Gary, Your comments are legitimate, but to the folks affected the issues are very serious.
Paul posted that there were coaches in JAX that were being reskinned. Previously discussed was the fact that SOME early coaches had a production problem that caused the poor bond. If what Paul was told is correct:
"Apparently there are still plenty of coaches needing to be repaired. It was explained to me that the original adhesive had a tendency to become brittle over time, and then crack due to the expansion and contraction of the stainless, resulting in the problem. The question is; do all XLII's with the suspect adhesive have the potential to fail?
The replacement stainless is evidently installed using a different adhesive that stays more pliant, allowing the expansion and contraction of the panels without causing damage to the bond."
Then this problem will not go away, but will appear over time based on how a coach is used, where it is used, and how it is stored. I think it needs to be discussed because owners who have not had the repair need to be alert to the future need, and to make certain Prevost will stand behind it. I know from my two rivet coaches that temperature changes, especially when the coach is in the sun make the skin buckle, pop, and generally move.
A bonded skin has to be experiencing the same expansion and contraction. Our entire coaches can grow as much as 1/2" going from a cold condition to a warm condition. The bond between the skin and the frame needs to allow for this or it will shear and fail.
Slides are another issue, but the Prevost slides appear to be robust, so those problems likely relate to adjustments and tweaking. I know Prevost has had issues with the pin shape, with the retraction of pins, and with seal quality. I think once the slides on a coach have been upgraded to repair the minor glitches they are going to be OK, but owners should share their experiences so the other owners are aware of what has been done to perfect the slides. Prevost has acknowledged by their 4 or 5 generations of slides that the designs had issues. By now they have had years and miles of experience so it is likely the slides are as good as they can get them. i see no reason to keep the repairs or modifications secret because like the skins, at some point Prevost (Volvo) is going to stop picking up the tab for repairs and then whoever is left standing when the music stops is screwed.
The window issue is likely a supplier issue, and since it is such a small market Prevost just has to solve it. I seriously doubt if anybody such as International Bus will come up with their own fix.
