Jim, we too have the external Sunshades. They were measured and sewn right there on site, the only way to have them made for your bus.

Ours have Stainless Steel Snaps, and I have them on the front window and door windows. They work like a charm, and are very well worth the money.

It takes maybe 10 minutes to put them on, but well worth the effort.

We had a vinyl bag made to carry and store them in when not on the windows, very nice to keep them stored. DO NOT FOLD the window shades, always carefully ROLL THEM UP.
