I got the frame out, but It sure didn’t want to come out easily! Being the top one it is somehow hooked into the rubber molding above it. The glass shop is charging me $85. to replace the glass. My fear is that I will break it trying to re-install it. I went to the Keystone dealer and they said it is a Kinro window, not Lippert. They didn’t have any service info on it, so I have e-mailed Kinro to see what they recommend. If I do break it, I will put plexi glass in the second time! Wish me luck.
