1. A method for detecting a load status change of a trailer comprising:
responding to a first triggering event by storing a first snapshot of a portion of a trailer generated by at least one camera local to a vehicle including the trailer;
responding to a subsequent second triggering event by storing a second snapshot of the portion of the trailer generated by the at least one camera local to the vehicle including the trailer;
comparing the positions of the portion of the trailer in the first snapshot to the second snapshot and determining a deviation between the position of the portion of the trailer in the first snapshot and the position of the portion of the trailer in the second snapshot; and
identifying a trailer load status change as having occurred in response to the deviation exceeding a predefined magnitude.
