In Mecca this is what I was told:
The problem lies in the bonding of the front cap to the frame, a known problem. The bond is known to shear when overstressed. It needs to be redone which requires removing both windshields, possibly the dashboard also. New bonding putty is then injected and the front cap is clamped in place. Windshields are then reinstalled.
There is a possiblity that one or both windshields will be damaged in the process. If this happens it's your problem, Foretravel will not pay for new glass.
It's about a 12 hour job on a Unicoach. The more I think about the work involved in this, the more I think it's a screaming good deal.
This is what I was told by the service manager, I opted to not have this work done. They very carefully urethaned my existing gasket and windshield in place and I have had no further problems after 10K miles. I have also been careful not to drop my coach off the road shoulder which is how all this started. It was my fault, not a defect of the coach.
I talked this over with the very experienced guy who reinstalled my glass and glued it in. He told me I could do a semi repair by screwing through the glass into the ply backer which it is supposed to be bonded to. Said you could use screws and snaps for a windshield cover, that's what most people do. Makes me look at coaches with exterior sun screens in a whole nother way.
I will have Foretravel do this work if and when the problem reappears. When I got to thinking about how they diagnosed it so quickly, minutes, I wondered how they could know this is the problem without extensive measurement. I "think" how they tell is by tapping on the fiberglass with a metal object. When I did this it was immediately apparent where it was bonded and where it was loose.
It's an aggreviating problem, but a solvable one.
