So I know it's been a long time since I poted on here and this topic might be dead but I figured I'd provide an update.
ALL lights are now working! We looked over the built in power controller and found that the previous owner almost set fire to the place! He had connected ALL the grounds together I guess to make a super fuse or instead of replacing the broken one he piggy backed, not sure his logic.
I got a hold of 4 15/20 AMP rated fused holders pulled the panel with a friend and we connected it all properly. No more draining, and ALL lights work.
I even took an idea I saw here and purchased a small 12V fan and placed it in the corner near a window to help pull in the cool air in the sleeping area.
We also brough in a 3 inch foam matress to put on top of the bed for better sleeping.
