We wanted more insulation and light blocking than the curtain our Winnie came with, so based on a post here we bought some
insulated curtains and a
long curtain rodThe rod just sits in a nice slot on our cabover, so we haven't needed to do any mods or use a tension rod or anything. Then for driving we pit a hook on the wall behind the driver and use one of the tiebacks that came with the curtains. Works like a charm and is super quick for privacy on overnight stops.
We also have the Adco windshield cover that we put on for longer stays, especially where we have some direct sun. But we'd never mess with it for overnight.
