Got a used truck camper that I've got to make sure that the wiring is ok, I know very little about AC/DC current so I need to read up on it. Are there any good posts that help out? The only power source that I can see is a 3 prong rec. on the out side of the camper and I cant find where a battery box was. I've not been able to follow it yet but there is a battrey charger pluged into a wall socket under the sink, now thats were it doesn't make sense to me. So any wiring info that I can read will help, Thanks Jeff
