An extension coupling releasably interconnects a trailer to a tow hitch on a tractor vehicle. The coupling includes a mount that is secured to the trailer. An elongated arm has a proximal end portion secured to the mount. A connector pin is disposed on a distal end portion of the arm in order to mate with the tow hitch. A retainer assembly is secured to the arm and engages the tow hitch when the trailer is interconnected to the tractor vehicle so as to resist rotation of the arm relative to the tow hitch. The mount includes a flat base plate and a pair of upwardly projecting side plates disposed on the base plate. This mount then engages a hitch connecting station on the trailer. The invention includes a trailer provided with the coupling where the trailer has a housing, a wheel set and the hitch connecting station.
