ABSTRACT:
A trailer hitching apparatus having a pair of vehicle sighting rods attached to each side of the ball on the hitch of the vehicle and extending upwardly so that they are clearly visible to a person when backing up the vehicle. A trailer sighting rod is attached to the tongue of a trailer and extends above a trailer hitch coupling which will extend over the ball of the vehicle hitch when the two are coupled together. Thus, the top extent of the trailer sighting rod and the vehicle rods are designed to be approximately the same when in use. In one embodiment of the invention, an angled loading plate is attached to the hitch on the vehicle and extends upwardly from rear to front and has a load pin guiding rail thereon. An opening is disposed in the angled loading plate directly above the ball of the vehicle hitch. A loading pin is attached to the trailer tongue directly above the trailer hitch coupling which is attached to the tongue and this loading pin extends downwardly. As the vehicle is backed rearwardly, the vehicle driver will guide the vehicle such that the vehicle sighting rods will be on each side of the trailer sighting rod. This will cause the load pin to engage the top of the angled loading plate as the vehicle is backed up and the loading pin guide rail will guide the loading pin into the opening in the angled loading plate. As this is done, the trailer coupling hitch is lifted up over the ball on the vehicle hitch. When the loading pin drops down into the opening in the angled loading plate, the trailer hitch on the tongue will drop down onto the ball of the vehicle hitch.
