Bill - I have been towing for several years and have never seen anything like this. To be honest I have no idea what happened.  I had a locking hitch pin (Curt) and towed from southern FL to TN, through the curves and NC mountains with no issues.  How it unlocked is an absolute mystery and adding to that the pin was still with the BlueOx system. The lock was gone. I know I checked it before we left that day but certainly didn’t check it at the fuel pump.  The BlueOx worked as it was supposed to, the cables held and the emergency brake system on the AirForce 1 activated accordingly.  Wish I could tell you more.
