We've had the "trailer disconnected" warning come up on two trips now. The first time we were going down the freeway and I have no idea why it happened.
The most recent one was on a fairly smooth road, but the first 4.5 miles away from the campsite was a dirt road. So that could have shaken the connector lose just a bit. (on the good news front, that road liquefied everything in the black tank)
I'll have to see about rigging up a small bungee as others have done. The 7-pin on the TV is was new a year ago as I made the dealer replace the original because the cover was missing.
