There have been posts regarding the summer heat and we had good results with an evaporative cooler that we used during our time in the Rockies. That unit was originally for our Aliner. I have put together a larger unit that I hope will cool the entire camper (Vibe 6501).
The panel fastens into the camper window with the Fantastic Fan pulling air from outside, through the aspen media which is enclosed in the laundry hamper, er, heat exchange box. A small fountain pump circulates the water to keep the media wet. Everything runs on 12v so we can keep cool when dry camping.
This will only work in low humidity conditions (< 50%). Typical temperature differential is about 20 degrees between outside air and cooler discharge. Out in Utah, with temps around 90 and humidity in the teens the air at the outlet measured 60F!
