Batteries during storage

[GoalstoDreams]

I am sure this question has been asked before but I did a search and couldn't find anything.

When storing your MH for a few months (winter months) what should be done with the chassis and house batteries? Right now all three batteries are connected, but the house batteries are turned off.

I start it and take it on a short (15 min) road trip every month or so, but I haven't turned on the house batteries during those trips, and now I have a dead chassis battery. Haven't even checked the house batteries. Sigh.

Some context....I'm not new to the RV world, but new to this stuff as my husband used to take care of this stuff and now I'm doing everything solo (so be kind in your responses)....;)

Any help would be much appreciated. Thanks!

If they will not be in use, and not connected to a smart charger, I'd remove them and place them in a storage area that is not prone to freezing. I keep mine on the floor in a corner of the garage.
