storage for one month

I say leave everything on and plugged in. Turn the water suppy and water pump off. Not much different than if you were staying in it. Here in Florida you must have AC or everything mildews. I stored my motorhome this way for 8 months a year for ten years and it worked out fine.

What food would you leave for a month and still want to eat? Condiments maybe anything else ,not me! When in doubt throw it out!

Will leave coach for 3 weeks , May 1 to May 25 in Tucson. Temps get warm in May. Can disconnect everything, open roof vents, clean frig, batt off. Second option is leave plugged in, frig on, air cond on set maybe to 85 or 90 f. Folks with thoughts on this please comment. Thanks.

I think it depends on the circumstances.

With only 3 weeks in storage I think you can do whatever you want. I wouldn't think twice about shutting everything down and leaving the fridge open for only 3 weeks. If all things are equal though I would plug it in and leave it, that way you keep the food in the fridge!

I would leave your motorhome plugged in, air on, fridge on electric, etc. I wouldn't want the wood to be subject to 100+ temps inside, especially, in a dry climate.

Ours is in storage right now for about 2 months. It's in a garage with 30 amp service. I have one air set at 90 and I put three small buckets of water around to keep the humidity up (located in the desert).
I also put extra water in the toilet as it will evaporate by the time we get back. I close all the drains in the sinks and put a rubber cover over the shower drain to help against evaporation.

MM.

Don't forget to shut off the city water supply!!

If you are not paying for electric or can absorb the cost, might as well leave the AC on in the manner you posed. Tucson should be a bit drier climate than here in FL however. We leave the AC on at 85 to keep the humidity down in there.

When I do that I leave it plugged in, AC (both) set at 83, and fridge on....no sense in getting rid of all the food stuff. I see no reason not to do that and it works for me.

I would leave plugged in, refrig OFF, AC OFF, battery charger on, and roof vents open, if you have vent covers to prevent rain from entering. Too many things can go wrong with a refrig fire or an AC unit going bad and with the roof vents open, it will not get too hot. Put reflective covers over all windows and windshield to keep most of the sun out.

Plugged in will normally be the better option unless the costs are a budget breaker.
