Review on RV Door Window Cover Shade - Double-Sided 16 x 25 - Travel Trailer Reflective Window Shade Regulates Temperature - RV Window Coverings Protect Your RV from UV Rays - Easy to Install Sun Shade by Leo Black

Our camper has one of those raised bubble windows over the tub. And no air conditioning in the bathroom. In summer it's just a magnet for warmth, especially in the Chihuahuan desert. Yesterday it was literally 111 degrees (12% humidity) and 110 degrees, the actual air temperature today. The bathroom was hot. I installed this cover on the skylight frame this morning. Velcro means no drilling! Hooray! It fitted perfectly and completely covered the stupid hole in the roof. There are no gaps. Yesterday at 6 p.m. in the greatest heat - 111 degrees - it was 90 degrees in our bathroom. The rest of the van stopped at 82. However today 110 degrees outside at 6pm and 82 degrees in the main trailer. The bathroom was 84 degrees! Still hot of course, but much better considering the surface temperature of the sun outside.
