ABSTRACT:
There is disclosed an adapter apparatus for permitting a trailer or similar vehicle intended to be towed from a rear-mounted ball hitch on a truck to rather be coupled to and towed by a truck having a fifth wheel type hitch. The apparatus includes a gooseneck with a kingpin adapted to engage the fifth wheel mount of a truck, a gooseneck mounting element for receiving the gooseneck in a horizontally adjustable manner and two upright columns which are rigidly secured to the tongue of the trailer on either side of the ball hitch and on which the mounting element is slidably attached. The columns and the gooseneck arm are of steel with rectangular cross-section and slidably engage respectively in steel box-beam portions of the mounting element. Each column and the arm include holes which selectively match a pair of holes in the mounting element. A pair of pin elements secure the mounting element against relatively sliding movement. The pin elements may be secured in place by padlocks for security against theft.
