A housing and trailer system comprising a trailer and a housing. The housing includes a lower housing and an upper housing and may be positioned on friction-reducing members that reduce friction between the housing and trailer. The reduction of friction facilitates the housing to slide more efficiently on the trailer. A safety lever and linkage system operates to safely move roof support structures and raise/lower the upper housing. An adjustable cargo system is attached to a roof on the housing. The adjustable cargo system is adjustable to receive and/or secure different sizes of cargo.

An off-road trailer includes a lower frame, a housing positioned on the lower frame, an extendible trailer tongue with a ball hitch receiver, an upper frame positioned above an upper surface of the housing, a rear frame, and at least two wheels. The upper frame and housing may store off-road gear, such as camping accessories. The housing may have one or more retractable platforms that may receive additional gear. Due to the configuration of the lower frame and the wheels, the trailer may be configured to traverse numerous types of terrain due to its lightweight frame and maneuverability.

An improved trailer chassis assembly primarily constructed from extruded components including an extruded chassis rail component, a cross member component and a connector component. The component has a wall surface defining an interior channel and an opening in the wall surface extending through the wall surface to the interior channel. The connector component has a first region adapted to engage with the interior space of the chassis rail component, and a second region adapted to engage with the cross member component. The interior space of the chassis rail component is adapted to capture movement of the first region of the connector component in vertical and horizontal planes, and yields movement in the axial plane.

A truck bed trailer that includes a truck bed and a trailer frame is described. The trailer frame includes one or more wheels and may be designed to have approximately 60% of the truck bed floor in front of the wheel axles and 40% of the truck bed floor to the rear of the wheel axles.

A tugger train trailer including a support frame configured as a transport material cart entrained in a trailer train, which has a chassis with at least two wheels, and a lifting device configured to adjust the height of at least part of the support frame relative to the wheels. The lifting device may include at least one rotatable eccentric disc, which is supported on a cam roller. The eccentric disc may be installed on a shaft that is driven in rotation. The cam roller may be mounted on the support frame or a part of the support frame.

A trailer device is provided with pressure washing features and devices. The trailer device is convertible between at least a first and mode of transport, wherein a first mode comprises a towing mode, and a second mode comprises a push or manual operation mode. The device also comprises various on-board features and control systems such that a fully-functional pressure washing unit is provided that is easily transporting between locations.

Detachable adjustable-width motor assemblies. Some embodiments may be configured for retrofitting between two legs of a golf cart. Some embodiments may comprise a motor housing having a first motor disposed within the motor housing, a first drive shaft, and a second motor disposed within the motor housing having a second drive shaft. The assembly may further comprise a first housing mount configured to be connected to the first wheel leg and a second housing mount configured to be connected to the second wheel leg. The first housing mount and/or the second housing mount may be concentrically and/or slideably engaged with the motor housing and configured to adjust the width of the motor assembly. The first drive shaft may be configured to engage with and transmit torque to the first wheel and the second drive shaft may be configured to engage with and transmit torque to the second wheel.
