An adjustable motor mounting system having an adjustable motor mount and a gear box with a motor. The adjustable motor mount has a first plate attached slidably to I-beams on a frame of a semi-trailer and attached to a second plate with a hinge so that the second plate is rotatable relative to the first plate. A third plate is attached slidably to the second plate and has a mounting plate attached thereto. The gear box is attached to the mounting plate and to a landing gear crankshaft of the semi-trailer. The adjustable motor mounting system renders the gear box movable towards or away from the landing gear crankshaft, movable leftward or rightward of the landing gear crankshaft, and movable upward or downward relative to the landing gear crankshaft.

A motor vehicle includes apparatus for towing a trailer with a retractable drop leg. A backup camera captures a detection image with a field of view including the trailer. A vehicle controller detects an initiation of driving with the trailer being connected. A pattern memory prestores at least one image pattern indicative of an extended position or a retracted position of the drop leg. An image scanner receives the detection image when the initiation of driving is detected, wherein the image scanner compares the detection image and the at least one image pattern to detect whether the drop leg is in the extended position. A notification device responsive to the image scanner alerts a driver if the extended position is detected.

A vehicle leveling system includes a jack adapted to be mounted to a vehicle frame without modifying the vehicle frame. In a particular embodiment, the jack includes a first bracket adapted to urge against the bottom surface of the frame and a second bracket adapted to be mounted to a surface of the vehicle adjacent the frame. In a more particular embodiment, the first bracket includes a horizontal adjustment feature and the second bracket includes a vertical adjustment feature. In another particular embodiment, the jack is coupled to the vehicle frame via a bracket that is adapted to be mounted to manufacturer-provided apertures formed in the frame during the manufacture of the vehicle.

A low-profile trailer jack for preventing damage to a jack includes a jack module that comprises a plurality of nested sections so that the jack module is selectively extensible. A first coupler is coupled to the jack module. A second coupler is coupled to an upper face of a hitch assembly proximate to an orifice that is positioned through the hitch assembly. The second coupler is complementary to the first coupler. The jack module is configured to be inserted into the orifice, positioning the second coupler to couple to the first coupler to fixedly position the jack module within the orifice. A top of the jack module is positioned proximate to the second coupler. An actuator is operationally coupled to the jack module. The actuator is positioned to extend the nested sections so that a bottom of the jack module contacts a surface to elevate the hitch assembly.
