I would start at the truck since you don't have the problem any other time. The problem child for the Super Duties is the back side of the seven pin behind the bumper and it is not unusual for the ground pin to virtually rust nearly off. The plug comes apart so it is easy to see.
Connecting the truck is what provides the power. My money is on the tail light circuit shorting to the reverse light circut inside the camper plug.
