Ok. I'll post my $.02. While I realize this is better suited to the MH problem area, I thought I would post it here to see if maybe Mike or others had some suggestions.
I was cleaning out the coach with the DW after our last trip and commented on how I couldn't wait to have the windshield people back to replace the gasket locking strip they forgot. I wondered where the wind noise was coming from but got back to cleaning.
My wife was wiping down the dash area and exclaimed "I found something...but you are NOT going to be happy about it."
Sure enough, the new right windshield glass had separated from the new factory gasket. There was about an 1/8" gap running from the lower inside corner up about 22 inches or so and both the left and right "new" glass pieces had the lower curved edges of the gasket "pulling out" so that the gasket now had a "V" or "trough" shaped expanse between the outer surface and the glass.
BTW, the company that worked with me to get the glass replaced under our Comprehensive Ins. portion is shipping a NEW gasket and appropriate locking strip to the glass installers since the last installers also sliced the gasket with their razor blade.
Could the new glass be too small, wrong curvature, the factory opening too big, the new factory gasket wrong etc? This front cap is similar/the same as the later 2000-2001 millenium edition and a host of other GS's.
When the glass was replaced, the install looked great so WTF? (pardon my French)
