A cargo hauling system is dimensioned to fit within a bed of a light truck. The bin moves forwardly and rearwardly relative to the truck bed along rollers provided on a tailgate of the truck. The tailgate is modified by reinforcing a perimeter of the tailgate, adding rollers to the tailgate, substituting reinforced linkages and hinges for factory originals, and adding a support member that extends between the trailer hitch and tailgate.
