Update on phantom trailer.
Went camping Wednesday, and got home today. Brief excursion with our granddaughter.
Anyway, I had physically put it on "no trailer" since going to the dealer. When I plugged in the trailer Wednesday, and it immediately went to "default" trailer which is where my current trailer resides. Wasn't smart enough in the beginning to give a name to my then current trailer.
After arriving at the campground, and after unplugging, I get the message "trailer disconnected" or something similar.
Plugged it in this morning, got the "default" trailer message, and after arriving home, got the message trailer disconnected.
I don't know what happened. I'll just keep observing it and note if the problems reappears.
