BREAKING WINDSHIELDS IN DAMON ESCAPER

It sounds like your opening for the windshields are not sufficiently reinforced to prevent flexing. I have seen my friends windshield crack in his driveway on a 1998 Newmar Dutch Star when his wife racked the front by uneven leveling. I have heard of this effect on various MH's. Has yours cracked this way also or just while driving? I would check the amount of preload between the windshield and the frame where it seats. That opening may be wrong from the factory. If there is more than about an 1/8 in gap I would float in an adhesive around the perimeter of the windshield where it bonds to the frame and letting that cure before the final bond of the windshield. Prior to bonding I would also check the preload by raising the jacks in various positions to see if the frame area is racking. I would look at the dash and reinforce it if needed(mine was loose) it would help support the frame opening. Are you using a Butyl type adhesive with some flexibility or a high strength adhesive like an epoxy? Hope this helps.
