A detachable gooseneck trailer ( ) having a gooseneck ( ) and a detachable trailer deck ( ) utilizes a trailer attachment assembly ( ) to draw the trailer deck ( ) toward the gooseneck ( ) during attachment. The attachment assembly ( ) includes a pivoting carrier ( ) having a retainer leg ( ) with a rearward facing load carrier engagement surface ( ). A slide member ( ) is attached to the trailer deck ( ) and provides a forward facing slide member engagement surface ( ). As actuators ( ) pivot the carrier ( ) rearward, the load carrier engagement surface ( ) slides over the slide member engagement surface ( ). A latching mechanism ( ) utilizes an elongated latch plate ( ) pivotally mounted on the retainer leg ( ) to automatically latch the carrier ( ) to the trailer deck ( ). A latch biasing spring ( ) biases the latch plate ( ) toward its latched position, so that it automatically engages a catch ( ) mounted on the trailer deck. A lift mechanism ( ) utilizes lift actuator arms ( ) extending from the tops of the load carrier ends ( ) to push down carrier arms ( ) and support the gooseneck ( ) above the ground. A ride height lock assembly ( ) includes a pair of pawls ( ) and a pair of ratchets ( ) to lock the trailer deck at a desired ride height.
