A dump trailer comprising a goose neck adapted for removable coupling to a tractor unit and a dropped frame joined to the goose neck and extending rearwardly of the goose neck. A plurality of trailer wheel and axle assemblies are joined to the bottom of the rear of the dropped frame. Each of the plurality of trailer wheel and axle assemblies has left and right wheels suitable for highway travel. An open bed is joined to the top of the dropped frame for receiving cargo. The open bed extends below the goose neck and has a front and a rear opening for permitting discharge of the cargo from the open bed.

A pickup truck can include a bed that is configured to be rotatable. The bed can be defined in part by a first side wall, a second side wall, a front wall, a back wall, and a floor. The bed can include a standard position in which the first and second side walls of the bed can be substantially parallel to a longitudinal direction of the pickup truck. The bed can be selectively rotatable about an axis of rotation into one or more rotated positions. In a rotated position, the first and second side walls can be angled relative to the longitudinal direction. The bed can also be raised in an elevational direction such that a lowermost point of the bed is located above a chassis frame of the pickup truck. A rotatable bed can expand its uses and allow for convenient access to the bed from a desired position.

A pivotable bracket assembly adapted to be coupled to a vehicle bed includes a base, a frame, and a support. The frame has a first fixed end pivotally coupled to the base and a first free end. The frame can pivot about a first transverse axis. The frame can receive a container. The support has a second fixed end pivotally coupled to the base and a second free end. The support can to pivot about a second transverse axis. The second free end can slidingly engage the frame. Pivoting of the support about the second transverse axis causes the second free end to slidingly engage the frame and rotate the frame about the first transverse axis. The assembly is moveable between a stowed position and an angled position by pivoting the support about the second transverse axis.

A roof-top rail system has a fixed frame mountable to the roof of a vehicle and a moveable frame mounted to the fixed frame. Bearings attached to the frames may engage channels formed in rails of the other frame in a manner such that as the moveable frame slides backward relative to the fixed frame, the moveable frame extends from the back side of the fixed frame. Simultaneously, a back end of the moveable frame rotates down as it extends from the fixed frame to improve access to cargo securing features of the moveable frame.
