Looking for a better way to cool your RV or Camper? Here are the items we bought and love. Those sun blockers for the windshield, work so much better than our regular pleated curtains, they literally lower our inside tempature by 10-12 degrees! We bought 2 sets so that our side windows would be covered. We also purchased a portable air conditioner and put it in the corner of our slide out by our dining table, perfect up to about 102 degrees, then when it got to 108 last year, we added a sprinkler on the roof, perfect comfort!
