In terms of troubleshooting, my trailer (not that old, 2016) worked flawlessly with my old truck and Prodigy P3. As soon as I switched to the new truck I had problems. I assumed it was trailer/brakes related.
Took it to a trailer mechanic (not an RV shop), he had a once over everything, tested it and gave it a 100% clean bill of health. My 7 pin is in good shape. So that is what led me to it being a truck issue. Others on that forum have done similar exercises, and many have brand new trailers.
So while agree, much can go wrong in this "system" of truck/trailer, I am fairly confident it's the truck and some sort of software issue.
My hunch, unverified, is that the resistance threshold for the truck knowing a trailer is connected is too low. And it's bumping in and out of thinking the trailer is there or not.
