Embodiments of the present invention provide a safety support apparatus for a cabin over engine (COE) truck cabin elevated in a raised position. The safety support apparatus provides a base member having a clamp mechanism which adjusts to truck chassis designs with rails of varying thicknesses. The frame of the safety support apparatus provides a receiver which may engage the bottom of an elevated truck cabin. The frame and base member are adjustable to allow configuration on either side of a truck cabin and deployment of the support apparatus at a range of angles.

A deck plate assembly for a truck chassis having first and second elongated frame members. Elongated rail brackets are mounted on the upper ends of the first and second frame members. Each of the rail brackets has an elongated slide slot formed in the inner sides thereof. A storage box and an airline box are positioned between the first and second frame members. A storage box support frame is slidably mounted in the slide slots of the rail brackets so as to be positioned over the storage box. The storage box is bolted to the storage box support frame. An airline box support is slidably mounted in the slide slots of the rail brackets so as to be positioned over the airline box. The airline box is bolted to the airline box support. Metal deck sections may also be slidably mounted in the rail brackets.

An extension bracket for a slider bar comprising a first curved tubular member affixed to a first end of a slider bar and a second end extending below the slider bar, spaced from a wall of a tractor unit. A second curved tubular member is affixed to a second end of the slider bar and a second end extending below the slider bar, spaced from the wall. There is a tubular cross member affixed to a portion of the first curved member to a portion of the second curved member. There is a tubular mounting member having first and second ends connected, respectively, to the second end of the first curved tubular member and to the second end of the second curved tubular member. The tubular mounting member also has a mid-section between the first and second end sections which is in contact with the wall of the tractor unit.

A trailer for use with a truck has a wheeled chassis having at least one wheeled axle at a rearward end of the wheeled chassis. A body has a cargo deck supported by the wheeled chassis. A camera is mounted to at least one of the wheeled chassis and the body so that a field of view of the camera includes a tractor when the tractor is operatively coupled to the wheeled chassis.

A cab and hood suspension system includes a cab suspension system, a hood suspension system, and a hood tilt system. The cab suspension system includes supporting spring elements and cab linkage configured to control movement of a cab relative to a chassis. The hood suspension system includes hood linkage configured to locate the hood relative to the chassis. The hood linkage is configured to match the movement of the cab linkage. The hood tilt system is provided by the hood linkage of the hood suspension system.
