Claim:
1. A modular trailer-hitch utility system comprising: a plurality of Female Building Blocks, said Female Building Blocks being durably constructed from 2½″×2½″ square tubing, each Female Building Block having four connected surfaces with a substantially square cross-section, and two open ends opposed to one another; a plurality of Male Building Blocks, said Male Building Blocks being durably constructed from 2″×2″ square tubing each Male Building Block having four connected surfaces with a substantially square cross-section, and two open ends opposed to one another and each said Male Building Block being sized to nest or mate inside of said Female Building Blocks; a plurality of Connectors being constructed, temporarily or permanently, from at least one of a Female Building Block and a Male Building Block; said Connectors being configurable in “L”, “T”, and “X” configurations, wherein the “L” connector configuration is comprised of two or more of a Female Building Block and a Male Building Block arranged to have two openings, with the two open ends orthogonal to one another; the “T” connector configuration is comprised of at least two of a Female Building Block and a Male Building Block arranged to have three openings, with two of the openings being orthogonal to the third opening; and the “X” connector configuration is comprised of at least two of a Female Building Block and a Male Building Block arranged to have four exposed openings, with each of the four openings being orthogonal to two of the other openings; and, wherein the connections made by said “L”, “T”, or “X” configurations are either fixed rigid, or pivotable; a plurality of Extenders, said Extenders being durably constructed, each said Extender being sized to either nest inside a Female Building Block, or fit over a Male Building Block; wherein at least one of a Female Building Block, a Male Building Block, a Connector, and an Extender can mate and nest inside a hitch receiver; and wherein more than one of a Male Building Blocks, said a Female Building Blocks, a Connectors, and an Extenders can be temporarily connected to create one structural members that can do at least one of extend parallel with the hitch, extend orthogonal to the hitch, extend both parallel and orthogonal to the hitch, pivot about one connection, and articulate by pivoting around more than one connection.
