Comes with Traditional series bed rail mount for clear bed when removed.
The 12K SuperGlide is designed specifically for the new shorter than a short bed trucks - like Ford's F-150 SuperCrew, Toyota Tundra, and Nissan Titan. It moves up to 22-3/4" while turning. Utilizes SuperRails, totally removable, leaving completely smooth, clean bed when done towing. The SuperGlide automatically moves the trailer away from the cab while making turns - allowing up to 90 degree turning without stopping, slowing down or even thinking about the space between the truck & trailer - and then automatically returns the hitch and trailer to the safe towing position over the truck axle when the turn is completed.
