Reese M5 16K Fifth Wheel Hitch

This is the 20K Companion configured for industry-standard rails, so it needs rails already bolted in the bed. Once mounted it tows with the same cushioned, articulating head and chucking-free ride as the puck versions.

The 20K SuperGlide rail unit is the auto-sliding short-bed solution for rail-equipped trucks pulling up to 20,000 lbs. It moves the pivot automatically on turns to keep the trailer off the cab; you'll need rails in the bed and the slider adds heft.

The 24K SuperGlide rail version brings PullRite's automatic short-bed slider to trucks set up with standard rails, self-sliding on turns for full cab clearance. Tows great for 24,000 lbs, but you need the rails installed and the auto-slide head is heavy.

The 14K SuperGlide is the lightest-duty auto-slider, made for short-bed trucks pulling smaller fivers up to 14,000 lbs on standard rails. It self-slides during tight turns to protect the cab and tows quiet; you just need the rails and accept the slider's extra mass.
