ABSTRACT:
An extension coupling for interconnecting a trailer to a tow hitch carried on a tow vehicle includes an elongated arm having a first end and a second end. The first end is pivotally connected to the trailer. A king pin is connected to the second end. The king pin includes a projecting stop that engages the tow hitch to strictly limit pivoting movement of the elongated arm relative to the tow hitch. In one possible embodiment, the elongated arm is a pin box assembly.
