Got this idea from a previous blog on an outside windshield cover (http://www.cheaprvliving.com/blog/als-creative-vandwelling-modifications-adco-rv-windshield-cover/).
I made outside window covers for our RoadTrek 190V out of solar screen--for front, back and one side window. Screens are cut slightly larger than the window and button magnets are glued on to the edges to make for fast & easy install/removal. Besides cutting out most of the heat gain they allow you to still see out (from inside) but not so from the outside. This is what I used but I'm sure other types would work:

My first attempt at these used regular ($5/roll) walmart screen door screen. These helped but actual solar screen worked much better--screen 'holes' are smaller and the vertical threads are about 3 times thicker than the horizontal threads.
