We have snap on sun screens on the outside of the windows including the dash, both driver and passenger windows, the door, and All slideout windows that are on the short sides of the slideouts. We also have full view Carefree window awnings that shade all the rest of the windows including the bathroom, two bedroom and four living room windows. In the living area two long awnings cover two windows each. Together all this will drop the temp inside the coach ten to fifteen degrees and our roof airs keep the coach comfortable even in the bright 90 degree full sun here at Hatteras Island. The inside of our coach is usually around 74-77 during the day...DW likes it to be cool!
