A tractor trailer system includes a tractor and a trailer. The tractor includes a hotel device and an Auxiliary Power Unit (APU) configured to provide electrical power to the hotel device. The trailer is connected to the tractor, and includes a Transport Refrigeration Unit (TRU) having a TRU controller, an electrical TRU component, and a TRU Power Unit. The TRU controller is configured to utilize the APU to provide electrical power to the electrical TRU component during low TRU load conditions, and utilize the TRU Power Unit during high TRU load conditions.

An air quality system includes an air precleaner, a filter identification component, and a control module. The air precleaner has a precleaner housing and a filter disposed inside the precleaner housing. The filter identification component is positioned within the precleaner housing at a first position and is mounted on the filter. The control module is positioned within the precleaner housing at a second position and is configured to emit an electrical field and communicate with the filter identification component via the emitted electrical field.

A trailer truck is the combination of a truck and one or more trailers used to haul freight. A trailer attaches to the truck via a trailer coupling (hitch), with much of its weight borne by the truck. The result is that both the truck and the trailer will have a distinctly different design than a rigid truck and trailer. Exemplary vehicles are provided, such as heavy duty trucks having truck bodies with improved aerodynamic characteristics, including improved drag coefficients.

An adjustable bunk is adapted for trucks or other vehicles equipped with a sleeping compartment. The bunk has a front end and a foot extremity and includes at least a first segment, pivotally connected to a second segment, by a supple connection, wherein the first segment may be in a horizontal position or in a non-horizontal position, while the second segment remains in a horizontal position. The first segment of the bunk is suspendable on an upper support placed above the bunk.

A motorized expedition vehicle has a truck cab, an engine and riding gear package, and a cabin. The cabin can serve any as a living, camping or office area. The wherein the cabin is expandable and collapsible between expanded and collapsed extremes. To do this, the cabin has an openable rectangular box structure. Namely, there is a rectangular and open-topped lower-sidewall/floor portion, a rectangular and open-bottomed upper-sidewall/roof portion, and one more rectangular-hoop shaped, intermediate sidewall sections. A crawlspace hatchway is formed between the cabin and cab.

The disclosure relates to a bunk, in particular for a vehicle cabin. The bunk comprises a base plate, an upper layer, a plurality of supporting members vertically compressible and spaced apart from one another substantially over the whole surface of the bunk, a plurality of pressure sensors which are part of the upper layer and in an adaptable area comprising at least one area of the bunk, a moving mechanism configured to move at least some of the supporting members in the adaptable area parallel to the base plate, and a control unit connected to the pressure sensors and the moving mechanism. The control unit is configured to cause the moving mechanism to move the supporting members in the adaptable area as a function of the current pressure data provided by the pressure sensors, to locally change the density of the supporting members to provide a locally variable bunk firmness.

Systems and methods that provide a deployable fairing system to a tractor trailer. The deployable fairing system includes an actuator used to extend the deployable fairing from an unextended configuration to an extended configuration to occupy a portion of a gap area that exists between a tractor and an attached trailer. The deployable fairing includes deployable upper and/or lower horizontal assemblies that are pivotally coupled to a frame attached to the tractor/cab, and two side panels that are pivotally coupled to one or both of the upper and lower horizontal assemblies. The deployable upper and lower horizontal assemblies and the two side panels fold in on one another along multiple hinged axes in the unextended configuration, and extend rearward from the top and sides of the tractor in the extended configuration to cover a portion of the gap. The fairing may advantageously flair from front to the rear.

A truck cabin comprises a driver's seat, a bunk, and a frame, the frame comprising a rear structure delimiting the rear of the cabin along a longitudinal axis of the cabin. The bunk has the shape of a rectangular cuboid, with two parallel lateral faces, a front face, a rear face parallel to the front face, a lower face, and an upper face parallel to the lower face. The bunk is located between the driver's seat and the rear structure and extends along a transversal axis of the cabin, alongside the rear structure. The bunk is rotatable between a horizontal position, in which the upper face is horizontal and oriented upwardly, and a vertical position, in which the upper face is vertical. In the vertical position, the lower face of the bunk is oriented towards the rear structure and the upper face is oriented towards the driver's seat.

A recreational vehicle has a floor and a vehicle body with a pair of walls, a roof, and end shells disposed at the front and rear ends of the walls and roof. Each wall has a plurality of horizontal members each extending at least part way between the front and back end of the respective wall and a plurality of spaced apart vertical bows each extending at least part way between the bottom and top of the respective wall. Each of the vertical bows has an inner surface and an outer surface with a recess defined in the inner or outer surface, the recess configured to receive one of the plurality of horizontal members therein such that the horizontal member does not extend beyond a portion of the inner or outer surface adjacent the recess. An outer wall skin is attached to the outer surface of the bows or members.
