A configurable trailer system which includes a chassis supported by one or more axles and any combination of an enclosed trailer, a camper, a livestock trailer, a dump bed and an open-sided trailer. The chassis includes a support surface and, at corners of the support surface, a plurality of locks. Each of the enclosed trailer, camper, livestock trailer, dump bed and open-sided trailer includes a plurality of corner castings configured to selectively and securely couple with the locks. A method for configuring the trailer system includes placing a first one of an enclosed trailer, a camper, a livestock trailer, a dump bed and an open-sided trailer on the chassis and locking to the chassis by engaging the locks with corner castings provided to corners of the first one of the enclosed trailer, camper, livestock trailer, dump bed and open-sided trailer.

There is proposed a towable expandable accommodation or storage assembly that includes a floor portion that is affixed to or supported on a drawbar, wherein an expansion portion is configured to be pivoted to one side of said floor portion to form at least one wall when the assembly is being used for the purpose of accommodation or utility. The assembly may provide a collapsible ablutions cubicle or kitchen area that can be reduced in size during transportation of the assembly. In this way, the assembly can be towed to a site and expanded to provide an expanded living area. Furthermore, the configuration of the floor portion means that grey water can be captured for the ablutions cubicle or kitchen area for storage in a tank or to be directed to a drain.

One aspect of the invention provides a mobile clinic including: an intermodal container defining at least a first opening and a second opening; a partition wall located within the intermodal container, the partition wall separating the intermodal container into an anteroom and a treatment room; and an access control device programmed to prevent passage from the anteroom into the treatment room until a user's donning of personal protective equipment is verified. Another aspect of the invention provides a collapsible structure including: a rigid base; a rigid roof; one or more collapsible walls extending between the floor and the base; and an erector system comprising four cross-bars. Another aspect of the invention provides a crate including: a bottom panel; a top panel; and a plurality of walls, wherein at least two of said plurality of wails including one or more conduits.

A recreational vehicle holding tank drain clearing assembly includes a tube having a first end, a second end and a perimeter wall. A first mating member is attached to the first and engages a first connecting member of a holding tank drain. A second mating member is attached to the second end and engages a drainage conduit. A cap is removably coupled to the second end of the tube. An air inlet is mounted on the cap and is fluidly coupled to the tube. A closure is mounted on the tube and is positioned in a first position preventing fluid movement through the tube or in a second position allowing fluid movement through the tube. Air is injected into the tube through the air inlet such that the air removes material trapped in the holding tank drain to increase flow from the holding tank through the holding tank drain.

The present embodiments provide a vent cover with an integrated drain tube attachment. The vent cover provides a structure for fastening or attaching a drain tube and guiding condensate from behind the vent cover in a controlled fashion. The structure is provided on a cover for connection of a drain tube rather than allowing the drain tube to simply float behind the cover. This positioning allows for controlled drainage in a manner that is preselected and retains the drain tube in a desired position.

A trailer includes a housing including an internal frame and an external frame. The external frame is coupled to the internal frame. In certain embodiments, the internal frame is positioned between interior panels and exterior panels of the housing. In certain embodiments, the external frame is spaced from exterior panels.

A pivotable wheel mount assembly may include a mounting bracket and a swing arm coupled to the mounting bracket. The swing arm may be movably coupled to the mounting bracket or the trailer and to a wheel and/or suspension so as to enable the wheel to be rotated from a downward or operational position to a horizontal or stowed position. The assembly may include an actuator support bracket coupled to the mounting bracket and an actuator that provides mechanical assistance moving the wheels between positions. One or more locking mechanisms may be provided to secure the assembly in either the operational position, the stowed position, or both.

A recreational vehicle may include a chassis, at least one axle assembly, and a vehicle body. The vehicle body may be supported by the chassis. The axle assembly may be coupled to the chassis and may provide motive support and underbody clearance to the chassis. The chassis may include a plurality of longitudinal main rails that span at least a portion of a length of the recreational vehicle and define a length of at least one crawl space. The plurality of lateral crawl space cross members may extend between and interconnect the plurality of longitudinal main rails and define a width of the at least one crawl space. A floor of the recreational vehicle, the plurality of longitudinal main rails, and the plurality of lateral crawl space cross members may collectively define the at least one crawl space.
