It wouldn't be so hard, would it, to have airplane style pull screens for vans? that way, you can have the color match (white default ofourse). could be installed inside the window, within the first 1/2" of the inside or inside the frame voids.. i dunno, haven't gone to the drawing board yet. Seems to be a no brainer, would provide total black out, and such a cool obvious choice for stealth camping.... would look like some made a cargo van from a window van from the outside - being the same color right inside the glass.
nobody in here but us chickens! just a thought! I'll start a kickstarteR campaign... WHOS IN???
