I know WeatherTech sells those thin windshield covers, but they don't insulate well and don't blackout around the edges.
I'm thinking of cutting out slightly oversized 2" hobby (open cell) foam and 'squishing' it into the windshield and side windows when I want to sleep in my vehicle, and hopefully it will expand back out to blackout around the edges. Anyone have any tips or experience with something like that? It's going to be a lot of foam, so I guess I'll have to store it up against the rear ceiling while driving?
