Abstract: A mounting fixture for a pickup truck that has a bed that includes a front wall, a rear tail gate and a pair of side walls that diverge at a given angle from the tail gate toward the front wall. The fixture includes a pair of support units mounted upon each bed side wall that extends along the length of the bed. Each unit further includes a horizontal flat platform that is attached to an associated side wall and a side rail that extends downwardly from the platform into the bed. The side rails converge from the tailgate toward the bed front wall. Parallel guideways are formed in the platforms and side rail for slidably receiving various components therein.
