A fifth wheel trailer hitch apparatus includes a support attachable to the trunk compartment, a platform connected to and supported by the support, a hitch ball mechanism, including a hitch ball attached to an extension member which is slideably communicating with the platform for movement of the mechanism between a retracted, lower position and extended, raised position, extended and retracted position securing devices to secure the mechanism in the extended and retracted positions respectively, and a coupling device for coupling the coupling mechanism of the trailer to the hitch ball. A coupler device includes an annular collar split into two portions, the collar being mateable with an intermediate narrow protrusion portion of a fifth wheel male end, a coupler with a tubular end for encircling a portion of the annular collar and an opposed ball end with an inner side forming a zone of a sphere for mating with a portion of a first hemisphere of a hitch ball collar attachment for attaching the collar to the tubular end of the coupler to sandwich the annular ring portion between the collar and the tubular end, an annular ring member with an inner side forming a zone of a sphere for mating with a portion of a second hemisphere of the hitch ball and a ring attaching device for attaching the annular ring member to the ball to sandwich the ball between the ring member and the ball end to permit the ball to rotate therebetween.
