Winter storage

[Hardhead417]

In the past I have been able to keep my campers plugged in over the winter. However, this year I have an Isata 3 which is my first Motorhome. I don’t have any problems with winterizing, but my question is about the batteries. The unit is stored inside without power available. The battery isolation switch still leaves some draw on the house batteries. Should I periodically charge the batteries or is it ok to allow them to drain. From what I understand that can reduce battery life.

You definitely do not want the batteries to drain. Disconnect the battery cable, pull the batteries out to store at home, or use a battery disconnect on the negative terminal like the one below.
