Abstract: A cargo carrier assembly (or "carrier") is externally carried at the rear of a truck. The carrier comprises a frameless L-shaped rack in combination with a wheeled container specifically adapted to be pivotably loaded onto the rack by using pivot latches which matingly receive locking pins fixedly secured to the container. The rack comprises either a single integral L-shaped support beam, or a compound beam. The compound beam, in turn, comprises a combination of (a) a pivot strut one side of which is attached to the frame of the truck and (b) an integral L-shaped support beam comprising a transverse strut and a longitudinal strut upon which latter strut only, the container is pivotably disposed. Only a portion of the base of the container is either directly supported on the struts of the L-shaped rack, or supported on pivot pins. Though the container may be secured with only two pivot latches, it is preferred to use, in addition, an attachment latch.
