A shooting support includes a hitch-supported lower tube insertable into a vehicle hitch tube, an upper tube pivoted to the lower tube for angular adjustment toward the vehicle, and a table pivoted to the upper tube. The two pivots each include an arcuate slot around the respective pivot, and a clamp with handled nut for clampingly fixing an adjusted position. The upper tube also includes telescoping extendable tubes and a clamp for fixing its length. By this arrangement, a user sitting on the tailgate can infinitely adjust a length and angle of the upper tube to position the table at a desired horizontal and vertical location relative to the table and to the tailgate. A side handle on the upper tube is in a balanced position when the tubes and table are folded to parallel positions, such that the shooting support can be easily carried.
