My wife and I are new to motorhomes having recently April 15 purchased the MH below: Auto Trail Frontier Arapaho We love it but don't really have a clue what we are doing. Did our first trip to Cornwall in July and think we got on really well for our first time. Then in August we went to Spain using the tunnel and travelled down and back through France, had a couple of mishaps didn't close the small toilet window correctly and found it missing on our next stopping point. Then we managed to get a flat battery, I think I left the lights switched on when I turned the ignition off, but I'm not sure. Fortunately we were on a site plugged in to electric so eventually it recharged and we were off again. We have had it parked on the drive and been checking the vehicle & leisure batteries and they seemed okay, we put it into storage about three weeks ago and after about a week we got a signal from the tracker to say the battery was flat. Sure enough when we went down both were flat. We didn't shut the system down as you would for winter as we are going away soon after the new year. If anyone has any ideas what we might be doing wrong we would be very grateful.
