It has been my experience for long term storage to disconnect all batteries rather than having the rig plugged in. I also disconnect the chassis battery.

Regardless of the type of batteries you have (let's NOT get into Lithium please), it is best to have them fully charged during storage. If the storage is longer than 90 days or so, that means "topping them up" every so often. I do it once a month.....when I move the rig about 18 inches to help prevent permanent tire flat spots.
