Abstract: A mounting system for a conventional tailgate of a pick-up truck is capable of situating the tailgate so as to minimize drag and at the same time provide effective use of the tailgate. Two mounting brackets are each structured to include a base for being mounted upon the top end of a respective sidewall of a pick-up truck cargo bed. Each of the mounting brackets is further structured with a particular fitting for interfacing with reciprocably shaped fittings on the tailgate to removably secure, in a selectively lockable manner, the tailgate to the fittings, in the same manner that the tailgate conventionally attaches to the conventional fittings located at the inside wall of the sidewalls of the pick-up truck.
