The first time I used our caravan overnight was at the docks overnight prior to boarding early next morning, i had on only interior lights but next morning couldn't start the car, a jump start worked and I let the engine run for over an hour. Could I have
a faulty leisure battery or a duff split relay? I am very new to caravanning!
