Renting a Class C and using the generator/ ac for pets

That is why we have 12v fantastic fans installed. We try to find a shady spot to park, and do run the generator if necessary. If the power goes off, the fans will take most of the hottest air out, drawing outside air in to replace it. That usually keeps it at or below the ambient air. Then we always consider where we are, and how hot it is expected to get, and especially how long we expect to be gone. There are a lot of times we just decide that leaving them is not a good idea.
