Features
- Machined wrap-around jaws: B&W machines the jaws to fit the king pin closely, leaving no room for slop between pin and jaw, so the trailer has less to bang against when you start and stop.
- Cam-action handle: A cam in the handle does the locking. With the handle shut, the cam holds the jaws locked on the king pin so they cannot let go by accident. Swing it open and the cam moves aside, freeing the jaws to let go of the pin when the truck drives forward.
- Shock absorber and bushings: A shock absorber lets the coupler shift side to side without banging, and polyurethane bushings under the coupler absorb rough pavement. A smooth ride was B&W's stated goal for the design.
- Two-piece design: Base and coupler head come apart. Pull the two saddle lock pins and the head lifts off the pivot arms by the handles on either side, which makes the base easier to remove or swap.
- Rated by B&W: B&W rates this Companion for 20,000 lb gross trailer weight and 5,000 lb pin weight. Know your truck's own towing rating too, and never tow past the lower of the two.
- Built and tested in Kansas: B&W builds the Companion in Humboldt, Kansas, and certifies its fifth wheel hitches to SAE J2638, the industry standard for fifth wheel and gooseneck hitches.

About B&W Trailer Hitches
Roger Baker and Joe Works founded B&W Trailer Hitches in 1987, working out of a garage where they built custom truck beds; the company name comes from their initials. Customers wanted a gooseneck ball that would not sit welded in the middle of the bed, and their answer was the Turnoverball: it mounts beneath the bed, and the ball flips over to stow in the same hole it tows from. The Companion fifth wheel hitch came next and uses the same under-bed mounting.
B&W still builds its hitches in Humboldt, Kansas, from American-made steel, and Joe Works began handing the company to its workers in 2007; today it is employee-owned. B&W counts itself among the few hitch makers still building in America.

Frequently Asked Questions
Which trucks does RVK3710 fit?
B&W lists it for the GM 2020-2026 with the GM factory installed puck system: 2020-2026 Chevrolet Silverado 2500 HD; 2020-2026 Chevrolet Silverado 3500 HD; 2020-2026 GMC Sierra 2500 HD; 2020-2026 GMC Sierra 3500 HD. It is for factory puck systems only.
What is a puck system?
B&W describes it as a five-hole towing system that the truck maker installs on the frame, with the mounting points under the bed floor. This hitch drops into those points, so no rails are needed.
Do I need a lube plate?
No. B&W says the lube disc is up to you: it is cleaner, but a coat of automotive chassis grease on the hitch's top plate does the same job.
Why won't the jaws open when I pull the handle?
On uneven ground the king pin can bind slightly in the jaws, which B&W calls normal. With the handle open, the jaw tension is released even if the jaws do not visibly open, and they let go as you pull away.
Will it work with my short bed truck?
Many short bed owners tow with a Companion, B&W says. Cab clearance depends on where the king pin sits on the trailer, the trailer's width and corner shape, and how much tight turning you do. The slider models slide back 12" for that turning room.
Can I buy the base or coupler head on its own?
Yes. B&W uses the same coupler head (RVC3006) across the Companion line, so the base and the head are each sold separately, in fixed and slider versions.
Installation
Here's the short version. Follow B&W's install sheet (below) for the exact positions and hardware.
- Choose one of the six pivot-arm mounting locations in Table A1 and check clearance for each truck and trailer combination.
- Mount both pivot arms with the four threaded blocks, eight 1/2" cap screws and lock washers; once all screws are started, tighten and torque each bolt to 110 ft-lbs.
- Remove the latch pins from each side of the base, rotate the handles out and set the base over the puck attachment points.
- Hold the base down, close each latch handle and replace the latch pins; assemble the leveling kit and attach it to the cab-side flange of the driver-side pivot arm.
- Lubricate the pivot-arm bushings with high grade lithium grease and place the coupler on the arms.
- Attach the coupler handle with the two 3/8" x 1-1/4" button head cap screws and flanged lock nuts, then set the coupler resting angle with the spring on the driver-side pivot arm.
