A truck rack with a platform mounts over a pickup bed and within a pickup canopy, leaving a generally unobstructed view through the pickup rear window. The a platform is supported above the cab rear window in its store position but lowered on one end for loading as the other end pivots on a rack frame. To minimize valuable space within the canopy above the window, the platform locates in store position between upper frame members. Supporting legs are length adjustable to position the frame and platform above the rear window. Sleeves mountable to a truck bed side have a hole through the sleeve receives a frame leg. Each leg has a plurality of holes matching the sleeve hole. To select a preferred leg length in positioning the upper frame and platform above the rear window, a bolt passes through a selective leg hole aligned with the sleeve holes. To accommodate various pickup truck models having differing bed width dimensions, a plurality of frame mounting brackets securable to the bed sides extend inward therefrom with the frame legs mounted on the brackets interior of the bed sides and within the canopy.
