Here's the little fuse block--do you have one like it? The white wire is connected to the (+) side of the camper battery and energizes all the right sides of the fuses. Then each left side of the fuse goes to a different circuit. I'm not using one of them. The (+) wire coming out of the camper should also be connected to the ride side of the fuse block.
I wanted my camper to be a self-contained solar-cabin like the ski huts so I don't have any electrical connections between the camper and truck. Instead, there's a small (10 W) solar panel on the roof connected to a charge controller and to the deep cycle camper battery. I don't have a fridge or heater so the small panel keeps up just fine. The green light means it's fully charged so it has disconnected the solar panel to keep from damaging the battery. Solar panels usually put out a little over 20-volts so you don't want one charging a full battery--it can damage the battery.
I really like the solar-charging because the battery is always completely topped-off when I'm ready to use the camper. I like how the lights are always bright and there's plenty of voltage at the 12-volt outlets and for accessories and the inverter.
My parents' camper has the typical battery isolator system with the camper battery charging off the truck when it's running. It works well on road trips when there's a lot of drive time for the battery to charge. For the usual quick weekend trips though, the camper battery doesn't get a chance to charge much and it's been gradually draining the whole time the camper's been parked. That means dim lights, a slow water pump, and when I bring the inverter along it won't even work because the voltage is too low. My Dad often removes the camper battery, brings it inside and plugs it into the charger. I sure like the easy solar approach though.
Here's the camper battery location:
It's just a Wal-mart deep-cycle.
Also, I'm not sure if yours came with a table, but mine had the table base right in the middle of the floor. I would trip all over the base trying to walk around in the camper, and with the table set up, it took up the whole aisle so I couldn't open the right cabinet or reach the cab-over. I completely removed the table and base for a while.
Just recently I started experimenting. With the table base at the very front of the floor and closer to the couch, I could move the mounting bracket on the underside of the table and I got it situated farther forward and closer to the couch so that there's plenty of room to get around it. I did some trial and error with the floor table base location to make sure that the hinged panel that comes out to support the lower bed could still move far enough forward that the bed doesn't catapult up with a misplaced knee or hand.
A pair of coat hooks mounted on the closet door stores the step ladder.
When not in use, the table stores just inside the closet, against the door.
Also, the floor is $10 of the cheapest vinyl tiles from Lowe's. The adhesive on them isn't the greatest so it's best to trim them enough so they're not crammed in otherwise they'll buckle up. Great replacement floor though and easy to clean.
