We spend a summer in N Mex sitting in the sun at about 5,000 elevation. Usual daytime temp was 95 - 108. The windshield is the biggest culprit for letting heat into the rv, even with curtains drawn. Get the reflectix for the windshield. It is sold in large rolls especially for motorhomes. That will make about a 10 degree difference. Keep shades drawn, have a fan moving the air around and you will be cooler. We also have insulation pillows in our vents to keep the heat of the sun from coming thru them. Skylight doesn't seem to be a problem with it's two layers. We are 36' with 2 13,500 btu and only ran the 2nd A/C late afternoon when the sun was shining on 1 side of the motorhome and onto the windshield. We were comfortable.
