A trailer assembly is described that includes a trailer bed, a gooseneck having an end portion connected to the trailer bed, and a coupling mechanism having a tail member attached to the end portion of the gooseneck. The tail member is located centrally and rearwardly of the end portion of the gooseneck and defines an engaging bar. The rear section of the trailer bed is provided with ground-engaging wheels disposed thereon in supporting relationship, and the front section of the trailer bed has guide means thereat comprising side walls affixed to the guide means and sloping upwardly therefrom, with the guide means being complimentary to the tail member and engageable therewith. The guide means also includes an aperature disposed on the upper side of the front section, and latch means mounted internally of the trailer bed proximate the aperture. The latch means has a latching surface extendable through the aperture for attachment to the engaging bar, and an activator is provided for activating the latch means to couple the latching surface to the engaging bar.
