Battery maintenance when gone

[Gdlow]

We will be in Apache Junction for the winter (most of), but will come home for a longer period of time to watch Grandson play BB. Typically I check the batteries every 2-3 weeks for water fill, but "may" come home for 6 weeks or so. At the same time, I will leave the rig plugged in, as we will have the refrigerator running...
Question Will the battery disconnect if shut off allow the fridge to continue running on electricity only, or what do you do in a situation like this?

Possibly run a dedicated line from power source to the frig and turn the batteries off and remove from ground.

gdlow, have you been having to add water when you check this often? If so, you have a problem and need to correct it first. Then you should have no problem leaving the coach for 6 weeks at a time. Here are some links to help with battery and charging info:
