Thanks for all the tips and advice. You answered our questions. We did get a piece of plexiglass and install it. We have since traveled to another stop with it, and it works fine. We plan to have a glass company install new glass when we get home.
Rod, I like your suggestions about the stained glass door window. I don't care for the one that is in there. I like to be able to see out, but would like to be able to cover it when the sun is shining directly on it. However, this was not the door window. It was the big window in the slide. So, no new door window for now But I'll keep that in mind. Hope to go to Wyoming someday, but probably not this year.
Len, thanks for your expertise on glass installation. Sounds better than ordering a whole new window from the factory, which we considered.
