solar help

[grey ghost]

I have a 2020 Montana 3121RL that has a solar panel with the shut off/on switch in the front battery compartment. My question is does any leave the solar power on while they are storing their rig? We usually use the camper every month or two so is it wise to leave the solar on to keep the batteries charged or should the power be shut off?
Thanks in advance!!! I'm sure this has been covered before but please be nice!

There is parasitic draw on the batteries even with the battery disconnect off. If you are not plugged into shore power, I would leave the solar active to help keep up with any draw while the camper is idle.

my power never gets shut off, the solar keeps the batteries topped off.
