Just returned from free camping at Bendella, Kangaroo Valley, weather came good and we had a perfect spot by the river, unfortunate we have a problem with 12V power. Only using 12V for lights and water pump, soon after set up 12V tripped out, inspected battery fuse, looked OK, replaced same battery fuse, problem seem solved but 5 min later tripped again, repeated several times with same result, checked for loose connection, thought again that problem was sorted but same fault repeated, after replacing and blowing several fuses I am now totally at a loss, I will contact auto electrician tomorrow, but if anyone has experince of similar problem then I appreciate your comment. Footnote, we purchased the van 1 year ago, its Dec 2009 build.
