The Defender Locking Gooseneck Coupler is listed in Work Truck Magazine Online. Three features of the new design were listed. 

• Integrated Lock - Push button keyed lock helps secure your investment with an integrated theft deterrent.  Lock your trailer coupler when coupled or uncoupled.
• Automatic Latch - Line up the ball, drop the trailer, and you're on the road!
• Cone-Shaped Coupler - Makes aligning and hooking up your trailer easier by widening the target.
