What do you do with the batteries in your 5er during winter? I live in Central OR and it can get pretty darn cold here at times. Do you leave them in the 5er and keep electricity to the converter or...
I live in a similar climate and I leave my batteries in the rig, fully charged, checked water level, and disconnected. I may charge them by switching the disconnect for 24-hours, once a month. My rig stays plugged in.
