A gooseneck extension device that increases the length of the available cargo space on a roll trailer, and enhances the ability to fully utilize the cargo space on a roll on roll off vessel. This results in the ability to carry more cargo per voyage.

A cargo vehicle is disclosed having a composite floor assembly with at least one conduit extending along a length of the composite floor assembly. The at least one conduit may include a first internal cavity and a second internal cavity. The first internal cavity may be configured to route at least one vehicle component. The second internal cavity may be configured to receive at least one vehicle component or a plurality of mechanical fasteners. The mechanical fasteners may be used to couple a base rail to the composite floor assembly.

A trailer is provided for accommodating different lengths of loads. The trailer can have a hitch assembly connectable to a tow vehicle, a deck assembly positioned behind the hitch assembly, an axle assembly having at least two axles and wheels provided on the at least two axles, a first kicker roller adjacent a first side of the deck assembly and positionable in a loading position and a transport position and a second kicker roller adjacent a second side of the deck assembly and positionable in a loading position and a transport position.

A trailer includes a chassis with at least one axle including left and right wheel and tire assemblies that support the chassis for rolling movement on a surface. A body is supported on the chassis and includes: (i) left and right sidewalls spaced apart from each other and respectively located on opposite left and right lateral sides of the body; (ii) a curved floor that extends between the left and right sidewalls; (iii) a bulkhead located at a front end of the body and extending between the left and right sidewalls; (iv) a tailgate located a rear end of the body and extending between the left and right sidewalls, the tailgate movable relative to the left and right sidewalls between an opened position and a closed position; (v) an open-top cargo space for containing an associated bulk commodity defined between the left and right sidewalls, the floor, the bulkhead, and the tailgate, wherein a dump opening of the cargo space is defined between the left and right sidewalls and is blocked by the tailgate when the tailgate is in its closed position and is at least partially unblocked when the tailgate is in its opened position. The bulkhead includes a one-piece aluminum alloy bulkhead sheet formed into a three-panel shape comprising a left panel, a right panel, and a central panel. The bulkhead includes opposite inner and outer sides, with the inner side oriented toward the cargo space. A respective obtuse angle is defined between the central panel and each of the left and right panels on the inner side of the bulkhead.
