A trailer positioning apparatus for aiding in aligning a trailer with a tow vehicle is disclosed. The apparatus comprises a pinion plate which is attached to the landing gear of a trailer; and a rack plate for contacting the ground. The rack plate and pinion plate are pivotally attached at one end. At another end, a pinion engages a series of holes in the rack plate in order to create relative movement between the rack plate and the pinion plate when a force is applied by a user. The trailer may be moved into alignment with the tow vehicle, simplifying the process of attaching the trailer to the tow vehicle.

The present invention relates to a hitch receiver alignment system having a first opening extending through and arranged upon a surface of the hitch receiver, a piston, a cylinder having a second opening adjoined to the hitch receiver, and a cylinder head having a third opening that is adapted to receive an alignment member that is manually adjusted by a user to contact the piston. As the user manually adjusts the alignment member, the piston consequentially is moved within a first opening extending through the hitch receiver. With the hitch being locked within the hitch receiver by a hitch pin, as the piston contacts the hitch within the hitch receiver the hitch is rotated about the hitch pin and a gap between the hitch and the hitch receiver is eliminated.

A hose nozzle test system having a housing with a plurality of hose nozzles therein. The housing has a first side for attachment of hoses to the hose nozzles and a second opposite side has openings which allow tips of the hose nozzles to extend out of the housing for the discharge of water. A diffuser may be attached rotatably to the second opposite side, allowing the diffuser to open and close to access the interior of the diffuser. A first portion of a trailer hitch is attached at a front end of the housing and a second portion of the trailer hitch is attached rotatably to the first portion so that the system can be rotated vertically for transportation by a vehicle or by an attachable wheel. The system is small, portable, stable, easy to use and maintain, and a user has control over where discharge water is flowing.

A disclosed hitch receiver assembly includes receiver having a worm gear and a slide bushing, a worm shaft engaged to the worm gear for laterally moving the receiver, a slide bar extending through the slide bushing and fixed at each end to a static structure, a hitch received within the receiver and a receiver pin coupling the hitch to the receiver and the static structure.
