A holding rack for mounting on truck tailgates is disclosed. The inventive holding rack is used with a truck bed to securely haul loads with a truck. The holding rack broadly includes a rack body for receiving the load, a hold-down mechanism that attaches to the rack body to engage the load, and a support frame. The support frame attaches to the tailgate and shiftably receives the holding rack and thereby permits placement of the rack in a stored position and in a load-supporting position where the load is secured while the tailgate is in its upright, latched position.
