Fish bowl cooling class A

I have to assume your 40’ motorhome has multiple rooftop AC’s or similar, as well as a generator sufficient to run all of them. Start the generators and turn on the AC units. If the dash AC has a recirculate option so turn that on too. As the cool air from the roof mounts get to the floor it should go up the return for the dash ac and help it cool better as well.

Where traffic conditions allow, we pull the side shades facing the sun down far enough to block the sun but not to interfere with viewing the mirrors. Do the same for the front shade down to help block out the sun.
