Tony, Sharon----We asked TCT about the possibility of swapping the windows to the other side, with screens on top, but they advised against it. Don't know if they had problems with their prototype or earlier builds. I looked all over the net for other builders who use this type of door, and all I could find (including Ebay sellers) was screen side down.
Tony, I see from your photos you have the screen side up top. No problems with heavy rain pooling or seepage during driving rains? Anyway, at this point, I'll put in my full size screen doors, and replace/respline the regular door screens, leave it at that. We always have the tear under an Ezup when we camp, and I'd rather have the doors open wide for the maximum of air flow.
Sharon, thanks for the compliment. I have some experience with commercial sewing (as well as household) and found a website that showed step-by-step how to sew a clear vinyl window into a covered boat enclosure. Dang if I can find it on my computer now---have to get going to work. Will look it up later and post for those who might want to do this themselves---was very helpful in planning out what to cut

and sew first on my screen door project.
