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.
Description & Fitment
B&W's Companion Single-Point Slider Fifth Wheel Hitch, part RVK3405, is rated to pull 20,000 lb GTW and carry 5,000 lb of pin weight. There are no rails: its post drops into the socket of an installed B&W Turnoverball gooseneck hitch, latches from the wheel well and is tightened with a draw-down bolt. B&W pairs base RVB3405 with coupler head RVC3006; the slider base lets the hitch slide back 12" for tight turns. Its six pivot-arm positions set the coupler from 17" to 19" high, per B&W's sheet.
Fitment & Compatibility
Check your fit: your truck has a B&W Turnoverball gooseneck hitch installed: the base post drops into its socket. B&W's sheet says this slider base works with every Turnoverball hitch except GNRK1309 and GNRK1257. On a Toyota Tundra with a composite bed (Turnoverball GNRK1222), B&W's sheet says to remove the base's polyurethane pads.
Not for: wedge-style or pivot-moving pin box couplers: B&W says not to use them with the single-point Companion. Other single-point Companions: RVK3500 (20K, fixed base).
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
What does RVK3405 mount to?
The socket of a B&W Turnoverball gooseneck hitch. It latches from the wheel well and a draw-down bolt tightens it, so it fits a hitch rather than a specific truck.
How far does the slider move?
A lever lets it travel 12" rearward for tight turns with a short bed. Keep it forward for normal driving: B&W says the rear spot is only for when you need turning room, because there the trailer's pin load sits aft of the rear axle.
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.
- Clean the truck bed, remove the polyurethane pads (not compatible with the bed geometry) and loosen the four 1/4" cap screws holding the pads on either side.
- Disengage the Turnoverball latch pin (driver-side fender well); with 2 or 3 people lift the slider base into the gooseneck hitch socket and square the legs with the bed ribs.
- Secure the slider base by tightening the 1/2" x 3-1/2" draw-down bolt to 80 ft-lbs.
- Choose one of the six arm locations (Table C1) on the carriage, set each pivot arm flat against the bolt plate, install four 1/2" x 2" cap screws and lock washers per arm, torque each to 110 ft-lbs and check truck-to-trailer clearance.
- Assemble the leveling kit and attach it to the cab-side flange of the driver-side pivot arm.
- Lubricate the pivot-arm bushings with lithium grease, place the coupler over the pivot arms, attach the coupler handle with the 3/8" button head cap screws and flanged lock nuts, and set the coupler angle.
