A wheeled trailer jack including a first foot pad and a second foot pad. The first foot pad including a first base and the second foot pad including a second base. The first and second foot pads rotatable between an engaged position and an unengaged position. When in the engaged position, the first base of the first foot pad and the second base of the second foot lie in substantially the same plane to act as a flat foot pad to stabilize the wheeled trailer jack and wheel chock to prevent a wheel of the wheeled trailer jack from moving. When in the unengaged position, the wheel of the wheeled trailer jack is free to move.

The example embodiment(s) relates to a method for monitoring the position of a jockey wheel of a trailer, including sensing a region lying behind a motor vehicle by means of a camera, processing the sensed image data by means of an evaluation unit and identifying the jockey wheel, and determining the position of the jockey wheel, comparing the sensed position of the jockey wheel with a secured position of the jockey wheel, and outputting a warning signal if the sensed position of the jockey wheel deviates from the secured position. The example embodiment(s) further relates to a camera system and to a motor vehicle including a camera system according to the example embodiment(s).

Aspects herein relate to using a three or more points to control the angular orientation of a structure via three or more jacks, and then stabilizing the structure via one or more stabilizers. In some aspects, the foregoing structure may include, for example, a motor home, recreational vehicle, travel trailer or fifth wheel trailer.

A trailer stabilizing device for stabilizing a parked freight trailer comprising a frame having mounted thereto at least a right side wheel and a left side wheel, the frame also including a hitch, a fifth wheel, and at least one of a repositionable wheel chock and a repositionable hook, the trailer stabilizing device further including a repositioning device in order to reposition at least one of the repositionable wheel chock and the repositionable hook. The present disclosure also includes a method of stabilizing a parked trailer at a loading dock, the method comprising: (a) positioning a wheeled trailer stabilizer underneath a parked freight trailer at a loading dock while landing gear of the parked freight trailer are deployed and a kingpin of the parked trailer is accessible; (b) securing the kingpin of the parked freight trailer to a fifth wheel of the wheeled trailer stabilizer; and, (c) deploying a repositionable hook operatively coupled to the frame of the wheeled trailer stabilizer so the repositionable hook couples to a cleat mounted to the ground, where deployment of the hook is operative to exert a pulling force on the kingpin.
