Guys,
Thanks for your help. We are trying to understand the purpose of that valance over the back rib that is in the nice photo you provided. I am guessing the rear window in the center does not unzip, and it looks like the windows are all a part of the rear top area and that the vinyl ribs are stitched to the window itself. I am going to study this a bit more. It would be great to be able to see under that valance!
Best,
Rex
