Ok you will not believe how much we do not know until we find out that something went wrong. We have been storing the caravan up at my parents property and I was going up to put what we did have in it and make the bed so we could stay on the weekends. By my surprise the you beaut battery system we have was flat. Yep we had only had the van for a week and the battery was dead. Rookies mistake on our part as we did not know any better that when then van is in storage you should disconnect the battery so it does not go flat and there was a little switch in the van which we were told to leave on that flattened the battery, hence we do not leave it on anymore. Luckily I worked out how to get the charge back in the battery and we were good to go.
