ABSTRACT:
A device for bringing the separated truck and trailer borne elements of a goose neck hitch arrangement fully into position for completing the mating of the two elements without requiring the vehicle operator to leave the vehicle; and then for completing the mating of the elements and locking the hitch into place with the vehicle.An open bottomed receiver well is located in the tow vehicle bed. The trailer borne hitch section that drops into the receiver well comprises a funnel shaped member having a rod shaped probe as its lower end. The rod shaped probe, dependent from the goose neck trailer tongue is used to visually align the hitch over the receiver well as the truck is backed beneath it. The driver then exits and the probe serves to guide the hitch into the receiver well as the trailer tongue is lowered toward the truck bed following which a pair of lock pins are used to complete the hitching.
