Abstract: A rack has a lower longitudinal truss which in use rests on an upright panel defining a forward part of the box of a pickup truck. A pair of upstanding members connect the lower truss to an upper truss which is parallel to the lower truss and spaced to elevate a load above the cab roof. The upstanding members are inwardly spaced from the ends of the lower truss and the ends of the upper truss are flush with the upstanding members so that a load will be centered in the truck box. A window guard is provided between the upper and lower trusses and is made of flat bar oriented so as to maximize visibility through the rear window of the cab.
