Mobilecastle - the sunshade that you show mounts inside of the camper. We had our dealer get a sunshade that mounts on the outside of the back window. It's a pull down that has locking pins at the bottom for stabilization when down. When traveling, we have it rolled all the way up. It's a great sun block and privacy blocker during the daytime - you can see out but folks can't see in. Hope this helps.
