Do you keep your coach plugged in when storing

Hey All,the storage unit I keep my Mountain Aire in has electrical outlets. Can or should I keep my coach plugged in while storing it?

I keep mine plugged in when stored. I shut off all the breakers except for the inverter/charger. That way all the appliances are not on, but it keeps all the batteries topped off all winter.

We have owned our current coach for 10 years. While in storage, it has been plugged in 24/7Öfor 10 years.

Like all that have already answered, my coach is plugged in while not out on the road. I don't turn off any breakers or do anything special. I have a 30 amp plug in my RV shed for hookup while in storage.

Agree 100% with the previous opinions. However if you have lead acid batteries make sure you're checking the fluid level on a regular basis.

I have a reminder on my phone to do it once a month and always have to add some distilled water.

If you have AGMs.....never mind.

I used to have my coach in storage with 30 amp power. On two occasions the breaker went off and the coach had no power for 2 days. The batteries were low but the coach would start of one time requiring 'battery boost". The staff at the storage place received an education on how to check the breaker.
I moved the coach home and has been on 50 amp. We get rare occasions when the house power goes out in a storm. I turn the fan and other power appliances which would be on the inverter. I did not have that option in remote storage.

Yes, always plugged in to 30a service at home. Everything turned off except the battery charge portion of the inverter and a small oil filled radiator style heater (UL approved) set to about 50 degrees. Also run a small fan set on low for air movement and a 100w Davis air dryer during the wet months.

I donít plug the coach in anymore. Since installing lithium house batteries, I simply plug in a maintainer for the chassis batteries, which can be isolated from the house batteries with the flip of a switch. I donít open either disconnect switch, but do turn the inverter off. After 2+ months the house batteries remain at a SOC that does not require charging.

The coach is stored in an enclosed building, on our property, and there is a 50A outlet inside. Iíve considered using a 100 watt solar panel to maintain the chassis batteries and foregoing the current maintainer. Before a trip, Iíll plug in to cool the refrigerator, I wonít charge the lithium batteries until we get to an RV Park. Unless weíre going dry camping.

In our case thereís no need to keep it plugged in 24/7.

We are lucky enough to have a spot in our yard for the coach. It's always plugged in, but we know if there is a power outage and can take corrective action.

Many who have theirs in storage have reported that they lost power, or someone unplugged their coach, and the batteries ran dead. Many storage facilities use a GFCI outlet which often doesn't play well with RV plugs.

If the facility has WiFi, I would install a camera or some other notification system so that you'll know if power goes out.

If maintaining power on the coach, and it's remote from you. A power monitor with notifications to your phone is a very good thing. Marcell and others.
