A/C

If you aren’t using the RV, why cool it?

I would just unplug. Check the water in the battery and use the disconnect.
TX grid needs a break.

The new units on the dealer lots are left the same way.

I will second that. Texas is short on Watts this month and if the grid fails again for sure they are gonna start "Emergency Pricing" again. I'm talking 10-20-30-More what you paid last month.

Ours stays plugged in year round. I keep the a/c set on 82 in the hot months. The residential frig stays on year round just like the ones in my garage and kitchen. I think it is better for residential frigs than shutting them down.
However, our fiver stays packed year round. The closet is full of both winter and summer clothing. The fiver is ready to roll at a whim. During the winter I use several damp rid buckets along with a small ceramic electric heater. It is under a shed out of the sun and weather.

Do yours like you feel is best.

waste of money to keep it plugged in.

My old camper had a crank out window in the living room and we installed a vent cover in the bathroom. Left the window and vent open year round, it was fine. No smells, no mildew stink, no black tank smell.

New camper is under a carport cover, so we leave the bathroom vent open and windows on the slideout open year round. Again, no smells and no issues.

I wouldn't run the AC unless I was worried about humidity. Even then, its probably cheaper to run a dehumidifier that drains into your largest holding tank (or run a hose to the outside). Keeping your RV cool when you don't use it is just a waste of money and electricity.

Get the vent covers (if you don't already have them) so you can leave them open even in the rain and leave them open. Don't bother leaving the fan running, hot air rises, so you will get natural convection.

Running the air/con provides no value and just consumes electricity.

I expect BRFNK has the same issue I do-----humidity. Our fiver is well insulated and with it being under a shelter out of the sun the a/c's only run periodically. I try to maintain 50 to 60% humidity by adjusting the temp. Over many years of doing so I have been successful in doing this over the summer months.
I don't sweat a few extra bucks over the summer since we are not home that much anyway.

Of course it is up to you but we leave our 3 vents and a couple of windows open during the summer months. Our RVs have always been stored at home, plugged in with batteries fully charged and fridge running for any whim departures during active RVing season. If someone is staying over we will run RV ACs for as long as needed, we don't fret the electric bill or the fuel bill, why would we even have an RV if that was the case.

I live in the country with a long dusty road so I can’t leave the windows open or it would look like a desert. I do have vent covers on top so that helps
