A selective filtration system for an operator cab attached to an agricultural vehicle. A HVAC unit supplies conditioned air to an operator space selectively from a CAT 4 filter and a CAT 2 filter. A pressurization blower and two way valve controls flow from the CAT 4 filter to the HVAC unit. Control of flow or isolation of the CAT 2 filter is provided by pressure variations within the system. The CAT 4 filter and CAT 2 filter are isolated from the ambient when they are not in use.

A sleeper panel is provided for use with each of the passenger and driver sides of a sleeper cab. The entire upper ends of the sleeper panels have a top flange which is secured to the underside of the sleeper cab. Structure is provided to maintain the curved portions of the sleeper panel in their desired radius of curvature. A cab panel is also described which is ideally suited for use on a truck cab so as to be positioned forwardly of the sleeper panels thereby providing an esthetic appearance to the vehicle.

Systems, methods, and devices for a vehicle door or window are disclosed herein. A vehicle includes a vehicle body and a cabin located within the body of the vehicle, wherein the cabin includes an interior that is configured to accommodate at least one person. The vehicle includes at least one seat located in the interior of the cabin that is configured for seating a user. The vehicle includes at least one door that provides ingress and egress to the interior of the cabin of the vehicle, and the at least one door is located with respect to the body such that the door opens to provide ingress and egress into the cabin from a backside of the seat.

A bunk system for a truck, comprising a structural board, wherein the structural board comprises a main portion having a main front edge, extending in the longitudinal direction, and a main rear edge; and at least a movable secondary portion linked elastically to the main portion, having a secondary rear edge, and a secondary front edge. The secondary portion is movable between a first position in which the main rear edge, the main front edge, the secondary rear edge, and the secondary front edge are substantially in a same plane and the secondary portion may move in at least one of a translation or a rotational motion into a second position in the event of a crash, thereby contracting the length of the bunk.

A plurality of different kits for assembling cabinets or support structures within the sleeper cab of a truck. Some of the kits are designed to support a refrigerator while other kits are designed to also support a microwave oven. At least one of the kits includes drawers for containing items. Other kits include support chests.

Systems and methods 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 battery powered auxiliary HVAC system designed to heat and cool at least a sleeper compartment of a vehicle such as a truck with a management system for conserving battery power. The management system includes a processor connected to temperature sensors, motion sensors, occupancy sensors, etc. for controlling a variable speed compressor, evaporator fan and condenser fan. A fuel fired heater is positioned between an evaporator coil in the inlet of an enclosure and the evaporator fan in an outlet of the enclosure such that air flow passes around the heater. The power electronics to operate the system may be actively cooled by connection tubing providing a heat sink between an evaporator outlet and a compressor inlet.

Systems, methods, and devices for a vehicle door or window are disclosed herein. A vehicle includes a vehicle body and a cabin located within the body of the vehicle, wherein the cabin includes an interior that is configured to accommodate at least one person. The vehicle includes at least one seat located in the interior of the cabin that is configured for seating a user. The vehicle includes at least one door that provides ingress and egress of the interior of the cabin of the vehicle, and the at least one door is located with respect to the body such that the door opens to provide ingress and egress of the cabin from a backside of the seat. Further, the door may be a cargo door, which allows access to the cabin for placement of a load, such as a cargo load on a pallet.

A vacuum cleaner assembly configured to be mounted in sleeper cab truck. The vacuum cleaner assembly includes a mounting bucket having a vacuum cleaner area having an angled surface and a hose storage area. A vacuum cleaner is disposed in the vacuum cleaner area and includes a collector module having a canister assembly and a vacuum module coupled to the collector module. The vacuum module includes a hose having an end, the hose extending from the vacuum module into the hose storage area of the mounting bucket. The mounting bucket is configured to expose the end of the hose through the hose storage area in any one of a plurality of arrangements to accommodate various mounting positions within the sleeper cab truck.

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.
