A vertical tapered trailer hitch coupling adapted for mounting on a vehicle hitch mounting frame. The mounting frame attached to an undercarriage at a rear of a vehicle. The vertical tapered trailer hitch coupling includes a vertical tapered collar with a four, equal sided tapered collar hole. A vertical, four equal sided tapered post is received inside the tapered collar hole. The post can be rotated 90 degrees in the collar hole. Mounted on top of tapered post is a trailer ball plate with a trailer ball. Also, the ball plate can include more than one trailer balls. This design allows for two different heights of drop hitches on a single hitch. The trailer balls are adapted for pulling different types of trailers behind the vehicle.

A towing device operably provided on a trailer for powering and controlling the trailer. The towing device has an actuator operably connected with the trailer during a towing operation. The towing device also has at least one switch provided in the actuator and operable to variably control at least one motor/generator provided on the trailer. The at least one switch is also operable to send a first signal to the at least one motor/generator via a first force exerted on the actuator by a vehicle, and wherein a first torque is applied to at least one wheel on the trailer via the at least one motor/generator being operably engaged with the at least one wheel. In addition, the towing device may include a controller operably connected to the at least one switch and to the at least one motor/generator, to control the torque applied by the at least one motor/generator.

A hitch is provided including a tongue, an insert, and a base. The tongue includes a C-shaped section having an internal spherical raceway and opposing walls, each extending from an opposite arm of the C-shaped section. The insert includes a spherical segment received within the internal spherical raceway and having a draw pin hole, and a projection extending rearward between the opposite arms of the C-shaped section and having a socket recess. The base being pivotally connected to the tongue through the opposing walls. The base includes a ball located in front of the pivotal connection, the ball being received within the socket recess of the insert, and a back end being adapted for connection to a towing implement.

A trailer system for providing transportability for a cavity cleaning and coating system may include a frame, a bed that is attached to the frame, a pair of ground engaging elements that are attached to the frame, and a lifting and reclining assembly that is attached to the frame that is configured to raise and lower the cavity cleaning system into position over a cavity.

A trailer pulling assist includes a jack that is vertically elongated. A bracket is attached to the jack and engages a tongue of a trailer. A wheel mount is attached to and extends downwardly from the jack. The wheel mount is rotatable about a longitudinal axis of the jack when the bracket is attached to the trailer tongue. At least one wheel is rotatably mounted on an axle of the wheel mount. A coupler is mounted on the wheel mount. An elongated handle is removably coupled to the coupler.

A trailer coupling mechanism includes a first end, a second end, a height adjustment assembly, a first swivel assembly, and a second swivel assembly. The first end is adapted to couple to one of a trailer and a vehicle. The second end is adapted to couple to the other of the trailer and the vehicle. The height adjustment assembly is coupled between the first and second ends and is operative to adjust the relative height between the first and second ends. The first swivel assembly is coupled between the height adjustment assembly and the first end and facilitates rotation of the first end with respect to the height adjustment assembly about a first axis. The second swivel assembly is coupled between the second end and the height adjustment assembly and facilitates rotation of the height adjustment assembly with respect to the second end about a second axis parallel to the first axis.

A lift and tow module for use with a trailer and method of towing a trailer with a truck. The module has an arm having a connection point for securing to a tow vehicle and a lift body having a connection point for securing the lift body to a trailer. The connection point comprises at least two connection mechanisms spaced apart on the main body for connection to corresponding mechanisms on the trailer. A support plate is extendable from and operably supported by the main body and the lift body is movable in reciprocal directions. Mechanical actuators are operably coupled to the body and the arm for controlling respective movement, which allows the module to jack up a trailer, connect to a trailer, and/or tow a trailer.

A trailer system for a vehicle includes a trailer having a trailer body, wheels, and a trailer tongue for hitching the trailer to a towing vehicle. A rear end of the trailer body is pivotally and detachably attachable at a rear of the vehicle. When attached at the rear of the vehicle, the trailer is pivotable between a stowed position, where the trailer is vertically oriented along the rear of the vehicle, and a lowered position, where the trailer is lowered such that the wheels are at the ground. When attached at the rear of the vehicle and in the stowed position, the front end of the trailer body is at or near an upper region of the vehicle. When attached and in the lowered position, the trailer functions to allow items to be unloaded from the vehicle and onto the trailer body.
