Cheap hot weather help
Back in the Phoenix area for a few months. Temps over 100 for the next week or so expected. Went out to Lowes and got a 24" x 25' roll of that reflective aluminum type bubble wrap insulation. Cut to fit windows on the sun side, placed outside, between the glass and the screen, latched the windows. Also cut and fit some for the skylights and the fantastic vents. What a difference! 105 is now actually comfortable with one a/c in a 30 footer! Thanks to a fellow rv'er for the tip.
