A trailer is disclosed which includes a first door with a first hinge configured to allow the first door to operate between an open position and a closed position, and a second door on the opposing side of the trailer with a second hinge configured to allow the second door to operate between an open position and a closed position. The trailer also includes a roof and a trailer tongue with a coupling configured to attach to a hitch of a vehicle. Two or more wheels are provided that are extendable from an up position to a down position. In this way, when the wheels are in the down position, the trailer is lifted off the ground. The trailer can thus change between at least three modes, including a first mode for storage, wherein the first door and second door are in the closed position and the wheels are in the up position; a second mode for ingress and egress, wherein at least one of the first door and second door are in the open position; and a third mode for travel, wherein the first door and second door are in the closed position and the wheels are in the down position.

One embodiment is a passive particle separation system including a plenum; an inlet for feeding outside air into the plenum, wherein the outside air has particles entrained therewith; a housing for enclosing the plenum; and a standpipe installed on the housing. The outside air enters the plenum via the inlet and plenum, housing, and standpipe interact to impact the outside air entering the plenum to cause the particles to be released from the outside air.

Vehicle, in particular a motor vehicle, which is equipped with a tailgate which can be pivoted on the rear of the vehicle. The tailgate can be pivoted by way of a pivoting device, around a pivoting axis between a closed position, in which a loading surface of the rear of the vehicle is defined, and an open position in which the loading surface of the rear side is open. In order to pivot the tailgate, the pivoting apparatus includes at least one pivoting arm on which the tailgate can be moved in a translatory manner and can be detachably held in place.

A rear door of bodies of lorries or lorry trailers, with at least one door leaf, which is hinged on the body to pivot about at least one vertical door axis provided in the corner region of the body. In order to mount accessories, advertising surfaces or lateral air deflectors, preferably in the region of the main closing edge of the door leaf, a supporting frame is hinged to pivot about a vertical frame axis, which supporting frame extends horizontally and substantially as far as the outer wall. In this lateral region, the supporting frame has a projection along at least part of its height, which projection engages in a groove-like recess congruent thereto on the body or on a component connected thereto, when the rear door is closed ready for travel.

A device for determining the position of a rear door or liftgate of a cargo truck or trailer includes a base attachable to the rear door or liftgate. A visual indicator extends from the base so as to be viewable from a side view mirror of the truck to enable a driver of the truck to determine the position of the rear door or liftgate due to the position of the visual indicator. The visual indicator may be a plurality of closely spaced apart elongated members, which may be brightly colored or light transmissive so as to be easily seen.
