Variable sized trailer ball hitch assembly

A method of attaching an interchangeable ball hitch assembly to a vehicle hitch, comprising the steps of:

• connecting an elongate shaft to the vehicle hitch, said elongate shaft having a first end extending from said hitch;
• providing a ball hitch body having a first ball with a first diameter and a second ball with a second diameter, said first diameter being different from said second diameter, said first ball connected by a stem to said second ball, said stem including opposing flat walls, said stem having a cross-sectional dimension less than each of said first diameter and said second diameter, each of said first ball and said second ball having an outermost end surface, said body having at least one elongate bore extending inwardly from each of said outermost end surfaces, said body having a central axis extending longitudinally through each of said first ball, said second ball, and said stem, said bore being generally concentric with said central axis;
• inserting said first end of said elongate shaft into said body from said outermost end of one of said first ball and said second ball;
• and
• attaching said first end of said elongate shaft to said body.

An interchangeable ball hitch assembly for connecting a hitch of a towing vehicle to a trailer, said ball hitch assembly comprising:

• a body having a first ball and a second ball, said first ball and said second ball connected together through a stem, said body having a central axis extending longitudinally through each of said first ball, said stem, and said second ball, said first ball having a first diameter, said second ball having a second diameter, said stem having a cross-sectional dimension, said first diameter being different from said second diameter, said cross-sectional dimension being less than each of said first diameter and said second diameter, said first ball and said second ball each having a respective outermost end surface, each of said outermost end surface of said first ball and said outermost end surface of said second ball being substantially flat and oriented in a plane substantially perpendicular to said central axis of said body, said body having at least one elongate bore extending inwardly from at least one of said outermost end surfaces, said at least one elongate bore being generally concentric with said central axis of said body, said at least one elongate bore including a single contiguous bore extending from said outermost end surface of said first ball through to said outermost end surface of said second ball;
• an elongate shaft having a longitudinal axis, a first end, and a second end, said first end extending into said at least one elongate bore from one of said outermost end surfaces and attached to said body;
• and
• a bolt, said bolt having a head and an externally threaded bolt stem, said first end of said elongate shaft containing an internally threaded hole threadingly engaged with said bolt stem, said bolt head having flat side, said flat side of said bolt head engaging one of said outermost end surface of said first ball and said outermost end surface of said second ball.
