Was out camping this past weekend and had an unusual issue. Woke up early to go hunting with a friend while the wife and daughter stayed at the trailer. Get a text saying trailer has no power they are running into town to go shopping. I keep hunting for a bit then return and notice no power to anything. We are dry in the woods with no hookups. Check all the breakers and fuses and all looks good. Little confused now as we two batteries and only spent one night there so far. check the light on the tongue jack as it is wired directly to the battery and it is dead. Hook up the generator to the batteries and the light comes on. Let it charge while having a beer and scratching my head. After charging for quite awhile things go back to normal indicator says full. We then go to bed and about 4am trailer goes dead again. What is going on. Hook the generator up and go back to bed. Thinking something is wrong we decide to head home first thing in the morning. While hooking up to the truck I discover the problem. Some how the breakaway pin got pulled. So the brakes were being powered and it was killing the batteries.
