Are you checking all this with the truck engine running and the truck camper battery disconnected at the battery posts?
Truck running, camper batteries still connected but kill switch flipped. I’ll disconnect the batteries and check again.

Hey Joe, I had the exact same thing happen. The wires were switched from the reserve Batt to the camper charger. I ran the fridge down twice on 12 volt before I realized something was wrong. Everything else worked just like you say. On the truck side Black to positive post and white to frame. Should be fine on the camper side. I looked and looked but couldn't find it but then I found it going through the truck floor. By sight it was perfect, running my fingers to the wires they were switched.
Good luck!
Joe
Edit, It made my alternator make a high pitch sound. Almost undetectable but after I fixed it it stopped.

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.

All sorts of personal events got in the way of me providing an update, but all is well now so here it is:
I replaced the 40 amp mini breaker that the pigtail connects to when it first enters the camper. Then I futzed around with the Separator unit to check connections and the fuses. It’s a BlueSea Systems unit under the dinette bench.
Presto, everything works as it should again!
So, all is well and I am currently out boondocking in Utah.
Thanks to all who ventured opinions and hypotheses!

Also, I forgot to mention that I noticed when the battery voltages go below 12 V on the campers batteries, the Seperator shuts them off from the truck pigtail. I wasn’t accounting for that when I was expecting the batteries to charge off the truck no matter what. Live and learn!
