Hi, hope someone may be able to help. We have a Jobl Kampa and this morning had a flat battery. We have had the van for 12m and never had any problems before. we are wondering if the cause is the extra fridge we plugged into the 12v socket on the vans main power panel but we were hooked up to electric and thought that the 12v socked ran from the electric/leisure battery? I have called jobl but they don’t have anyone in until Monday who can answer for definite. Thanks in advance.
