A multi-component quick assembly trailer hitch guide for use with a trailer tongue having an inverted ball socket of a trailer and a trailer ball hitch on a vehicle includes multiple removably connectable sections each less than twenty four inches to permit economic shipping and storage.

A peripheral monitoring device according to one embodiment includes an acquirer configured to acquire a first rear image of a vehicle at first timing, the vehicle including a first coupler device which couples a towed vehicle; and an image processing unit configured to superimpose first identification information on the first rear image at second timing being after the first timing, the first identification information representing a position of the first coupler device at the second timing, and to display, on a display screen, the first rear image on which the first identification information has been superimposed, the display screen configured to be installed in the vehicle.

A vehicle is structured for exerting a force on a dolly to move the dolly along a ground surface includes a locking pin mechanism having a locking pin, and a dolly tongue receptacle coupled to the locking pin mechanism so as to be movable with respect to the locking pin mechanism to a first position and a second position. A switch is coupled to the dolly tongue receptacle and structured to be operated by movement of the dolly tongue receptacle from the first position to the second position. The locking pin mechanism is structured to extend the locking pin into an opening formed in the portion of the dolly tongue responsive to operation of the switch.

A coupler lock device is configured for use with a self-latching trailer coupler securing a hitch ball in the coupler socket. The coupler lock device has a housing that includes a top panel portion defining a cavity configured so that, when the housing is secured in position over the trailer coupler, the housing top panel prevents seating of the hitch ball in the coupler socket by restricting upward movement of the release lever when an attempt is made to insert the hitch ball into the coupler socket. Also, when the housing is secured in position over the trailer coupler with a hitch ball seated in the coupler socket, the housing top panel prevents removal of the coupler socket from the hitch ball by restricting upward movement of the release lever that would otherwise release the coupler socket from the hitch ball.

A modular skid mounted oil production system, comprising multiple skid sections that are connectable via alignment pins coupled to the skid beam structure. The alignment pins having a fork connector that is connected to a knife connector. When the skid sections are connected, the piping, electrical, and pneumatic tubing connectors are connectable to the other corresponding skid piping, electrical, and pneumatic tubing connectors without the need for welding or field construction of connecting components. The modular skid oil production system is capable of expansion or contraction as required by the operation of the system. For example the system includes removing a skid section having a larger separator and replacing it with a skid section having a smaller separator, without the need of welding or field construction of connecting components.

An improved anti rattle hitch pin assembly for a trailer hitch assembly enables a threaded member to be inserted into the shank receiver, and allows for an easy alignment of a threaded device to the side hole of the shank receiver. The anti-rattle hitch pin assembly includes an arc-shaped retainer wire, a threaded receiver pin, a threaded member, and an optionally lockable member. The threaded member can be easily moved to the alignment position once the internal components of the hitch pin assembly including the retainer wire has been inserted inside the shank receiver tube.
