Camper AND truck batteries dead

I assume you have unplugged the truck
So the converter and solar only have to charge the camper batteries

Something drained them, lights, fans, trailer brakes ? ..is the pin pulled out, it has happen to more than one person on here

MrWizard was right. It's never happened to me before, and when he mentioned it I didn't even realize what he was talking about, but somehow the Break Away switch pin got pulled, causing the electric trailer brakes to be on drawing all the power out of the batteries on the camper and the truck. Never happened in the 10 years I've owned the camper and I have no idea how it happened. Anyway, now that the problem is solved the batteries have charged up just fine, charging to 14.4 volts during the day and then dropping to 13.3 to float, and finally to 12.9 after dark. This weekend with heavy furnace use and a couple hours of TV each night, we woke in the morning with battery gauge reading 12.5. Not sure how much this episode shortened their lives, but for now it seems like the batteries are going to live:)

Thanks to everyone for all their thoughts on the problem, and special thanks to you MrWizard for hitting the nail on the head.
