Bedroom window sunscreen

[RBotr01]

Motorhome (FR Sunseeker) parked with the rear facing west. It is 90 degrees here today in the KOA near Williamsport. I moved the sunscreen from the cab back to the bedroom. It cuts down the greenhouse effect quite a bit.

DW and I are going out to get provisions later at a nearby Walmart where we will purchase another accordion fold truck size sunscreen.

Question: Has anyone seen custom sunscreens to fit the rear facing bedroom window? It would be nice to have a suction cup model.

Thanks!
