As a proud RV owner, I’ve learned that disconnecting the battery when my vehicle is parked for an extended period can significantly benefit me. First and foremost, it helps prevent battery drain. I’ve experienced the frustration of returning to my RV only to find a dead battery because I left something on or the system drained it while I was away.
