Hi, Just purchased my first camper van {auto sleeper warwick duo}parking it up for winter on my drive and not sure what I should do about leaving electrics on. I can plug in on mains but don't know whether I should leave control panel and fuse box on or off regarding keeping the batteries charged. I have had a caravan for about 12 years now, so understand about draining the water off, which I have done already, and taken all the cushion etc. out, any more advice would be greatly appreciated. Thanks
