I have a box AC attached to the top of my RV. Curious if anyone has some expert advice on how they keep their campers cool?
We have two A/C units on our Class A motorhome. They work well up until about 100 degrees. After that, we need a 3rd portable A/C unit. We survived 3 Arizona summers in our Class A with the 3rd portable unit - we put it at the foot of our bed so that we were cool enough to fall asleep.
