Full-time in the Arizona heat

We spent a summer in NM at 4,000 feet with temps of 95 - 108 most days of the summer. It was hot! We have a motorhome and put one of the foil insulated panels inside in the windshield - helped a lot. Also pillows in vents so heat from the sun didn't get thru, shades down. A/C running continuously with 2nd one running later afternoon when the sun hit us full force for a couple hours. The main problem we had was the refrigerator and morning sun on that side. Helped a lot when we could have the awning down, but sometimes too windy. We added another fan in the outside compartment at the bottom pushing air up. If it's in a slide, better shade that slide somehow. Of course parking in the shade helps, if you can find any. We won't do it again if by choice.
