We too often judge others by our experience.
We camp mostly in California Sierras, where at 4000' elevation we never need AC.
Even in San Francisco -East Bay area as of now (end of June) the nights are in 50's so our house gets cooled down at night and doesn't need AC when 90's in the afternoon hit.
But few years ago I did travel with my truck into Phoenix.
It was about 110F and base on my CA experience I planed to sleep in truck cabin.
It did cool down at 10 PM to 98F.
I had a choice of running engine with AC overnight, but calculated the fuel at the time at over $3/gal and hotel come cheaper.
Rare occurrence in other states, but happen.
So calculate generator running time into you decision.
Would suck to get up every 2 hr to refuel.
