Abstract: A trailer assembly including a load deck and a detachable gooseneck. The load deck includes a rotatable shaft and latch wedge and the detachable gooseneck includes a hook. The attachment of the gooseneck to the load deck will result in the rotation of the shaft and latch wedge and engage the latch wedge and hook preventing detachment of the gooseneck and load deck. Misalignment of the gooseneck and load deck may be compensated for by a chamfer of the hook and a v-shaped groove.
