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

I've hung out on hot days in my trailer, with no A/C, because it's still cooler than outside as long as it was pre-cooled with the A/C or windows opened overnight. It wont even warm up to ambient temp until evening hours.

There are wireless temperature monitors out there you could use as well, so you'd know if you need to come back. Or, even setup a baby monitor so you see how the doggies are doing, for temperature and other reasons.
