If on the west coast, take it to A-1 Auto Glass (Formerly Coach Glass) in Coburg, OR. Take I-5 North or South to exit 199, Go to the west, turn right at 1st traffic light. Go down and you will see them on the left in part of the old Monaco Plant Building. The Phone Number is 800-944-3230, explain you have an RV and it's an Alpine. I have had them do 2 of mine, they are the best. A normal glass shop cannot do the window correctly, and it will leak every time. These folks are the best, plus the sister company manufacturers the glass for about 80% of the bus and RV market, so they work with the manufacturers to get it right.
