A trailer hitch draw bar includes a receiver tube with a square cross-section to fit into a receiver on a vehicle trailer hitch. A vertically-displaced collar is fixed to the receiver tube and includes a generally square, vertically-oriented aperture and at least one set of horizontal mounting holes. A vertically-adjustable elevation tube is positioned within the collar's aperture and includes a plurality of horizontal holes that index with the mounting holes in the collar. At least one mounting pin is inserted into the collar's mounting holes and the indexed holes in the elevation tube. A hitch ball pad is horizontally fixed to the top end or the bottom end of the elevation tube. A reversible hitch ball is attached to the hitch ball pad. The receiver tube, the elevation tube and the hitch ball are each separately invertible to accommodate any hitch elevation requirements while eliminating a dead zone.
