An update for anyone who might still be curious about this. I disconnected both camper batteries and ran the truck to test voltage into the camper. It’s registering 14 point something volts so no problem there. I noticed the black wire connects to a post in the battery compartment and has another black wire coming off of it, so I tested the voltage at both of them and it’s OK. I also noticed from there, it goes under the floor of the camper to I don’t know where, then a different (?) black wire comes out of the floor and connects to a different post, before connecting to the fuse box. That wire at the post has zero voltage. So my best guess is something got disconnected under the floor and when I get home, I will take it apart and stick my head under to take a look. Appreciate all the thoughts and suggestions and when I’m home in a week or so, I’ll report back on whatever it is I find or don’t.
