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.

1. A cargo hauling apparatus for an associated motor vehicle, the apparatus comprising: a support member;a hitch configured for receiving the support member and for mounting the support member to the associated motor vehicle; anda self-tightening mounting assembly to mount the support member to the hitch, the self-tightening mounting assembly includes a fastener having a fastener head at a first end and a shank extending therefrom with external threads at a second end;a first wedge member including an opening adapted to receive the fastener shank therethrough, the first wedge member further including an angled surface that extends from a first, narrow end to a second, enlarged end configured for receipt in the associated hollow tube of the associated vehicle hitch;a second wedge member including an opening adapted to receive the fastener shank therethrough, the second wedge member further including an angled surface that extends from a first, narrow end to a second, enlarged end configured for receipt in the associated hollow tube of the associated vehicle hitch, the angled surface of the second wedge member disposed in facing, sliding engagement with the angled surface of the first wedge member;a fastener nut threadably received on the fastener threads and adapted for operative engagement with one end of the first and second wedge members, so that rotation of the fastener relative to the fastener nut in a first direction draws the first and second wedge members toward one another and the angled surfaces selectively expand outwardly in response to the fastener and fastener nut drawing the wedge members toward one another, the angled surfaces of the first and second wedge members selectively expand outwardly in response to the fastener drawing the wedge members toward one another; andwherein the self-tightening mounting assembly includes a hollow tube having multiple engaging pads that selectively move inwardly and outwardly through openings in a sidewall of the tube in response to movement of the wedge members to release or engage an inner surface of the hitch. 2. The cargo hauling apparatus according to claim 1, wherein the self-tightening mounting assembly includes openings through the first and second wedge members to receive the fastener. 3. The cargo hauling apparatus according to claim 1, wherein the angled surfaces of the first and second wedge members are adapted to engage an inner surface of the hitch in the perpendicular directions. 4. A cargo hauling apparatus for an associated motor vehicle, the apparatus comprising: a support member;a hitch configured for receiving the support member and for mounting the support member to the associated motor vehicle; anda self-tightening mounting assembly to mount the support member to the hitch, the self-tightening mounting assembly includes a fastener having a fastener head at a first end and a shank extending therefrom with external threads at a second end, a hollow tube having openings in sidewalls of the tube, a first wedge member including an opening adapted to receive the fastener shank therethrough, the first wedge member further including an angled surface that extends from a first, narrow end to a second, enlarged end configured for receipt in the hollow tube, a second wedge member including an opening adapted to receive the fastener shank therethrough, the second wedge member further including an angled surface that extends from a first, narrow end to a second, enlarged end configured for receipt in the hollow tube, the angled surface of the second wedge member disposed in facing, sliding engagement with the angled surface of the first wedge member, and a fastener nut threadably received on the external threads and adapted for operative engagement with one end of the first and second wedge members, so that rotation of the fastener relative to the fastener nut in a first direction draws the first and second wedge members toward one another and the angled surfaces selectively expand outwardly in response to the fastener and fastener nut drawing the wedge members toward one another, and multiple engaging pads that selectively move inwardly and outwardly through the openings in the hollow tube in response to movement of one of the first and second wedge members to release or engage an inner surface of the hitch, wherein at least two of the pads are provided and oriented to engage inner surfaces of the hitch disposed at ninety degrees relative to one another therein. 5. The cargo hauling apparatus according to claim 4, wherein the angled surface of at least one the first and second wedge members is adapted to engage the pads upon selective rotation of the fastener. 6. The mounting assembly of claim 1 wherein the angled surfaces are disposed in abutting, sliding relation with one another. 7. The mounting assembly of claim 1 wherein the first and second wedge members are identical.
