This is the sliding Companion for a short-bed Ram with the factory puck system. It drops into the four pucks like the fixed version, then slides back 12" and locks there so a fifth wheel trailer can turn hard without meeting the back of the cab. Rated at 20,000 lb gross trailer weight with 5,000 lb of vertical pin weight. Tow in the forward locked position and use the 12" of travel only for maneuvering at low speed, because sliding back puts the pin weight behind the rear axle.
What's Included:
Companion coupler head with machined wrap-around jaws (RVC3006)
Sliding base (RVB3670)
Pins, hairpins and mounting hardware

Features
20,000 lb Gross Trailer Weight, 5,000 lb Vertical Pin Weight B&W rates this hitch at 20,000 lb gross trailer weight with 5,000 lb vertical pin weight. Those are the hitch's numbers. What you can actually tow is the lowest of the hitch rating, your truck's own fifth wheel rating on the door jamb, and, on a rail-mounted hitch, the rails underneath it. The coupler head on this hitch, RVC3006, is itself rated to 25,000 lb; on this model the 20,000 lb figure comes from the base, which is why B&W sells 20K and 25K versions of the same-looking hitch.
Machined Wrap-Around Jaws The jaws are 1" thick and they wrap the king pin for full contact all the way round rather than gripping it at two points. That is what stops the chucking you feel through the cab when a loose coupler lets the trailer take up slack every time you lift off. B&W machines the jaws to the pin instead of relying on a wedge.
Cam-Action Handle That Releases on Uneven Ground A cam in the handle takes the bind out of uncoupling. Open the handle and the cam moves aside so the jaws can release as you pull away; close it and the cam blocks the jaw from opening at all. The practical benefit shows up on a sloped campsite, where a conventional handle can jam solid under load.
Shock Absorber and Polyurethane Bushings The whole coupler rides on polyurethane bushings, with a shock absorber taking the side-to-side movement instead of letting it slam. B&W set out to build the smoothest-riding fifth wheel hitch in the industry, and this is the part of the design that does it.
12" of Slide for Short-Bed Turning The base slides back 12" and locks there, which buys the trailer nose room to clear the back of the cab in a tight turn. Use it for maneuvering at low speed only and tow in the forward locked position: with the hitch back, the pin weight sits behind the rear axle and the truck handles differently.
Uses the Factory Prep Package, No Rails The base drops into the four pucks your truck already has, so nothing is bolted through the bed floor and no rails stay behind. Release the handles and the whole hitch lifts out, leaving a bed that is flat except for the factory pucks.
Two Pieces, So One Person Can Handle It The coupler lifts off the base without tools by pulling up on the saddle handles. That turns a hitch too heavy to shift in one go into two manageable pieces, which matters every time you take it out of the bed for the week.
Built and Tested in Kansas Made in the USA, built by B&W in Humboldt, Kansas. B&W's own testing goes past what SAE J-2638 asks for: rather than using a fresh sample for each test, it puts a single hitch through all three 300,000-cycle dynamic tests and the six static tests in sequence.
Fitment & Compatibility
Requirement
Detail
Truck
● Ram equipped with the factory fifth wheel and gooseneck prep package
Attachment
● Four factory bed pucks. The base drops in, the handles turn, the pins go in
Rails
✗ Not used. Nothing is bolted through the bed floor
Bed when not towing
● Flat, with the four factory pucks flush in the floor
Without the prep package
✗ Not compatible. A Ram with no pucks needs rails or a B&W Turnoverball under-bed system
Fit guidance: This hitch mounts to Ram's factory fifth wheel prep package and fits only a truck that has the four pucks in the bed. Ram's puck system also has adjustment in it that owners frequently miss, and a base that feels loose in the pucks is usually the adjustment rather than the hitch; there is a B&W film covering exactly that in the videos. Those are the hitch's numbers. What you can actually tow is the lowest of the hitch rating, your truck's own fifth wheel rating on the door jamb, and, on a rail-mounted hitch, the rails underneath it.

Installation
Type: Drops into the four factory bed pucks, turn the handles and pin · Time: About 15 to 30 minutes once the mounting system is in the truck · Tools: None for the hitch itself beyond the drawdown bolt wrench, plus a second person or a hoist for the lift · Difficulty: Straightforward, but heavy
Work from B&W's RVK3670 installation sheet in the Resources tab. The assembled hitch is about 267 lb, so lift it in two pieces: the coupler comes off the base by pulling up on both saddle handles, and each half is manageable on its own. Grease the polyurethane bushings on the pivot arms before setting the coupler down, check the pins and hairpins are all home, and do a pull test with the trailer wheels chocked and the landing gear down before you take it on the road.

About B&W Trailer Hitches
B&W Trailer Hitches started in a Humboldt, Kansas garage in 1987, when Roger Baker and Joe Works were building custom truck beds and wanted a gooseneck hitch that did not leave a ball standing up in the bed the other six days of the week. Their answer was the Turnoverball, a ball that flips over and stows flush with the bed floor, and it is still the product the company is best known for. B&W has built hitches in Humboldt ever since and is one of the last hitch makers still manufacturing in the United States.
The company has been 100% employee-owned since 2007, with roughly 500 employee-owners who have a stake in what they build. That shows up in how B&W tests. SAE J-2638 is only a recommended practice for gooseneck and fifth wheel hitches, and where the standard would allow a separate sample for each test, B&W puts a single hitch through all three 300,000-cycle dynamic tests and the six static tests, one after another. The Tow & Stow receiver line is tested to SAE J-684.
Prestige Truck is an authorized B&W Trailer Hitches dealer. Every hitch we ship is new, factory-packed, covered by the full B&W factory warranty, and supported by B&W's own service team in Humboldt, Kansas.
Frequently Asked Questions
Straight answers on specs, fit and support
How much can it tow?
B&W rates it at 20,000 lb gross trailer weight with 5,000 lb vertical pin weight. Those are the hitch's numbers. What you can actually tow is the lowest of the hitch rating, your truck's own fifth wheel rating on the door jamb, and, on a rail-mounted hitch, the rails underneath it. Pin weight is the part people forget: a fifth wheel puts roughly 20% of the trailer's weight straight down onto the truck, so check that figure against your truck's payload as well as its tow rating.
What do I need in the truck before this will mount?
You need a Ram with the factory towing prep package, the one that leaves four pucks in the bed. Look in the bed. If there are four pucks flush in the floor, you have it. If not, the truck needs rails or a B&W under-bed system, and this hitch will not mount to either.
Can I tow with it slid back?
No. The 12" of travel is for maneuvering at low speed, and you should tow with the hitch locked forward. Slid back, the pin weight sits behind the rear axle, which changes the way the truck steers and brakes. Slide it back to turn tight, then lock it forward again before you get back on the road.
How heavy is it, and can I get it in and out on my own?
It ships at about 267 lb, which is more than most people want to lift in one go. The design accounts for that: the coupler lifts off the base by pulling up on the two saddle handles, with no tools, so you move it in two pieces. Most owners take the coupler out and leave the base in, or take both out for a completely clear bed.
What maintenance does it need?
Grease the saddle through the grease zerk about every six months so the coupler keeps pivoting freely, keep the jaws greased with a multi-purpose chassis grease, and either grease the top face of the coupler or run a nylon lube plate on it. Check the pinned and bolted connections before every tow and look for cracks or damage. That is the whole routine.
Why buy this over a rail-mounted hitch?
The bed. A rail-mounted hitch leaves two rails bolted through your bed floor for as long as you own the truck. This one lifts out and leaves the floor flat, which is the difference between a truck that tows and a truck that also hauls. Rail hitches are cheaper, and B&W builds those too as the Patriot line if that trade suits you better.
