A tailgate hitch sensor system is installed by mounting a housing around the end of a receiver tube on the back of a hitch, and then plugging the system into both the OEM passenger side tailgate locking mechanism and the OEM driver side tailgate locking mechanism. A magnetically operated reed switch is positioned at the top of the housing, and a cover supporting a magnet is pivotally hinged to the housing so the cover has a normally closed position covering the receiver tube. When the cover is closed, the tailgate operates normally. When the cover is open, the electrical circuit for at least one stage of lowering the tailgate is de-activated.

A tow bar assembly has a shank portion for attachment to the towing vehicle hitch, a pivot joint on a trailing end of the shank, and two arms extending from the pivot joint for attachment to the towed load. A stowage block on the shank includes two transversely oriented slots, for receiving a tab on the arms and thereby hold the arms in a transverse, horizontal stowage position. The arms each telescope between extended and retracted positions. A latch, having a retention shaft with a handle, automatically engages to lock the arm in the extended position when the trailing end of the arm is pulled to the extended position. The retention shaft has a shape which, depending on its rotational position as controlled by the handle, either allows the telescoping or interferes with the telescoping, locking the arm in the extended position.

Tow bar assembly

A hitch tightener is used around the lip of a hitch receiver tube and a shank inserted into the hitch receiver tube. The hitch tightener has a U-bolt with two threaded legs, and a crossbar with throughholes for the legs of the U-bolt, positioned so the crossbar and the U-bolt encircle the shank and the receiver tube lip. A standard threaded nut holds the crossbar onto one of the legs, and a cam lock lever is pivotally attached on the other leg by a threaded trunnion nut. When the cam lock lever is pivoted from its opened position to its closed position, it moves the crossbar toward the connecting portion of the clamp component, tightening the hitch tightener around shank and lip.
