How to control climate for pets/ a cat

Open several windows so there may be a cross breeze.
In cold weather our cat would burrow under blankets.

Hello OP............one post no response

You & cat going to live in it ....... not at RV Park so WHERE?

Boodocking/dry camping
Parked on streets
Parking lots
What area of USA?
How long do you plan on leaving cat alone?
How do you plan on recharging trailer battery w/o any AC?

HOT Climate ..........even with windows open /fan running the inside of an RV can get pretty HOT


More specific info about HOW/WHERE you plan on RVng.

When we didn't stay at a RV park with electric and we dry camped we had a generator to use for AC power.
Plus we limited amount of time away from RV when dog was left alone.

But we are retired and can come/go as we please.

Most are just like a house, with a thermostat-controlled propane furnace; or if you need cooling, you'll need a generator to supply the electric for the A/C

since you don't have electric, it is quite simple. cold, furnace. hot, open a window. you don't have much option when you don't have electric.
