Simple Removal for Full Bed Access

B&W Companion Simple Removal

With the Companion from B&W, you get a heavy-duty fifth-wheel trailer hitch that mounts in your truck bed by connecting directly to a custom underbed mounting kit with the included components. No modifications are required to your truck or trailer. And no additional parts are required for the system to work. When you're done towing, the entire hitch can be removed for complete bed access.


Quiet, Secure Ride

The 1" thick jaw on the Companion is precision machined to provide a tight, sturdy connection. And unlike slide-bar models, the rounded 2-piece jaw on this fifth-wheel trailer hitch inhibits rattle and movement by securely wrapping around your trailer's king pin, resulting in easier hookup and a safer, quieter ride.


B&W Companion Bushings

In addition to the sturdy jaw, the Companion has durable polyurethane bushings built in to provide a smoother, more comfortable towing experience. These bushings sit on top of the pivot arms that support the fifth-wheel head. Because the head is resting on a padded area, it is able to pivot without clanking. The ability of the head to pivot - both front to back and side to side - along with the trailer also helps to limit the chucking that may occur with a more static hitch.


Non-Binding Latch Handle

The dual jaw on the Companion is operated by a simple-to-use cam-action handle. This handle allows you to quickly and easily release the jaws on the hitch, even if you are on uneven terrain. If any binding does occur between your truck and trailer, the jaws may remain closed after you move the handle to the open position. But because the handle is unlatched, there is nothing keeping the jaws closed except for the binding pressure. Therefore, simply driving your truck forward will be enough to force the jaws to open.


The cam-action handle is held in the closed position with the included pin and clip. For extra security, you can replace the pin with a sturdy padlock. The shackle on the lock you choose should have a diameter of 5/16", height of 3", and a width of 2-1/4".


Built-In Slider

Most often used on trucks with 6' beds, a slider helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a slider to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.


The slider that is built into the base of the Companion allows for 12" of fore and aft travel to give you the clearance you need.


Assembly of the B&W Companion

The Companion's pivot arms are what allow the hitch to be adjusted front to back as well as up and down for optimal positioning. As a result, this hitch can accommodate the height of your trailer and also help to give you some additional cab clearance. To adjust either the height of the hitch or the fore/aft positioning, just attach the hitch's pivot arms in the desired location on the base.


The hitch head installs on top of the pivot arms. When you have the head in position, simply secure it to the arms with the included pins.

Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches

B&W Turnoverball Gooseneck Trailer Hitch

B&W Turnoverball Gooseneck Hitch

Not only does this kit provide you with a sturdy, custom base for installing your Companion fifth-wheel trailer hitch in the bed of your truck, but it also doubles as one of the most recognizable gooseneck hitches on the market. This fifth wheel installation kit actually is the Turnoverball gooseneck hitch from B&W.


Gooseneck Specs:

  • Gross towing weight: 30,000 lbs
  • Vertical load limit: 7,500 lbs
  • Ball size: 2-5/16"

B&W Companion Installed in Turnoverball Gooseneck Hitch

With the B&W Turnoverball underbed gooseneck trailer hitch you get the best of both worlds. When you go to tow a gooseneck trailer, the Turnoverball creates a sturdy, dependable connection with your trailer. And when you're done towing, you can stow the ball upside down in the hitch to get full bed access and a clean appearance. When you're ready to tow your fifth wheel trailer, just install the Companion in the ball hole in place of the gooseneck ball and lock the post in place using the built-in handle. You can remove the fifth wheel when you're done towing, leaving your truck bed open once again.


Simple, Custom Installation

This kit is custom designed for your vehicle. The mounting brackets bolt to existing holes in your truck's frame. While some modification is required - you will need to cut a 4" diameter hole in your bed for the hitch ball and drill holes for the built-in safety chain loops - there is no need to weld onto or to drill into your frame.


Galvanic Corrosion Limiting Tape

Note: Because the body of your truck is constructed of aluminum, there is an increased risk of galvanic corrosion when a different metal, such as steel, contacts the truck body. To help prevent this corrosion, strips of polypropylene tape are included to provide a barrier between the steel of the hitch and the aluminum of the truck. These strips are to be applied to the center section of the gooseneck hitch as shown above.


Once you have the brackets and center section installed, set up the operating handle. This handle is designed to be accessed from the rear driver's-side wheel well. On the end of the handle is the heavy-duty steel pin that secures the mounting post of the Companion (or the base of the gooseneck hitch ball).

  • How to Measure 5th Wheel Hitch Height for a 2023 GMC Sierra 3500 W/ a Short Bed
  • Ok so in order to determine the correct height setting for your 5th wheel and your GMC Sierra 3500, you'd need to level your setup and measure from the ground to the bottom of the pin box and choose a height setting that gives you the most level ride (17" - 19" for the B&W Companion # BWRVK3400-5W you're looking at). Keep in mind that we recommend having at least 5-6" of space between the bed rails and your truck/trailer to make sure you don't have any contact between the two. Since

  • How to Determine Clearance for Gooseneck Hitch on 2016 Dodge Ram 2500
  • You need to use the following calculation to find if you have enough clearance: (A + B) - C = Clearance A = Distance from the gooseneck ball to the truck cab B = Offset used C = Width of the nose of the trailer divided by 2. So your A is 35" and C is 48" which means right now Clearance = -13". You really want A to be 4" more than C so in this case you need a 17" offset. Even if you combine an offset ball with an offset adapter you aren't going to be able to get to 17" or even 13". The

  • Troubleshooting 5th Wheel Chucking with Andersen Ultimate Gooseneck Hitch
  • The Andersen Ultimate is a nice option for being lightweight, but it is not any help with chucking as you described. It has absolutely no built in assistance for that function. You are pulling a really big trailer, so the chucking will be worse with that than a lightweight 5th wheel because there is simply more momentum so you will feel it more. There really isn't a way to help with the chucking you are experiencing with that particular hitch as air ride will definitely help some but

  • Will B&W Companion Fit 2006 GMC Sierra 2500 Short Bed
  • Hi Eric; I'm not sure where you saw that but we have had other customers successfully install the # BWRVK3400-5W without any issues. If the design of the bed on your 2006 GMC Sierra 2500 would not allow the installation of the Companion we wouldn't list it as an option and B&W would have notes saying the Companion is not compatible. You can definitely use this 5th wheel hitch with your truck.

  • Which B&W Companion 5th Wheel Hitch For 2024 Toyota Tundra
  • Hi Cory, There is a B&W Companion 5th wheel hitch that will work with your 2024 Toyota Tundra with a composite bed, though it is a different part number than the one you asked about, as that one is for Chevy/GMC trucks with a puck system. Instead, you'll need the mounting rails (which even doubles as a gooseneck hitch), and either a fixed or sliding Companion. You'll need the fixed hitch if you have an 8 foot bed, and the sliding hitch if you have a short bed. The correct parts to add

  • 5th Wheel Hitch for Clean Bed Once Removed on a 2003 Chevy Silverado 1500 Short Bed
  • If you are wanting to keep the bed of your 2003 Chevy Silverado 1500 clean then I highly recommend using the B&W Companion # BWRVK3400-5W because it mounts in the B&W Gooseneck Hitch # BWGNRK1059-5W. Instead of having bed rails in the bed of your truck you just have the gooseneck hitch ball receiver and safety chain loops as you can see in the attached photo. The Companion is made right here in the USA, has a 20,000 lb weight capacity (which is more than your pickup), 17" - 19" of height

  • How to Determine Correct Height Setting for 5th Wheel Hitch
  • Choosing the right height setting for your 5th wheel hitch is a combination of a few different variables. First of all you want your towing setup to be as level as possible. With your Montana High Country 340BH level you will want to measure from the ground to the bottom of your pin box where the king pin is at. The next step is to choose which of the 3 height settings on your 5th wheel hitch, 17", 18" or 19", gives you the most level ride. Simply measure from the ground to the head

  • Recommended B&W Turnoverball Gooseneck Hitch for a 2022 GMC Sierra 3500
  • No, I am sorry it will not. Your B&W item # BWGNRK1012 stops fitting the Sierra 3500's after 2019 when GM changed the frame size. For your 2022 GMC Sierra 3500 you will need the B&W Turnoverball Underbed Gooseneck Trailer Hitch item # BWGNRK1020. I have linked an installation video below to help you get it set up. To make towing with a gooseneck or 5th wheel trailer easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C53CR. This harness puts a 7-way

  • Fifth Wheel Hitch for B&W Turnoverball Gooseneck Rails in 2008 Ford F-350
  • The B&W Turnoverball Gooseneck # BWGNRK1108-5W also serves as the underbed rails for the B&W Companion and does not fit other fifth wheel hitches. Don't let the lack of options dissuade you though because this is the fifth wheel hitch I would recommend for you even if you did not already have the base rails because the Companion is considered by many to be the highest-quality fifth wheel hitch available and height should not be an issue because it can adjust from between 16-1/4" to 18-1/4".

The B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W can be used in a 2013 Ram 2500 longhorn short bed, provided you have a B&W Turnoverball gooseneck hitch installed in the bed.

  • Recommended 5th Wheel Hitch For A 2023 Ford F-250 Super Duty
  • You can only have one pivoting point between the trailer and tow vehicle so that means you'll have to decide between a slider hitch and locking out the Turning Point or getting a fixed hitch and using the Turning Point as a rotating pin box. The Turning point pin box is going to offer you almost twice as much turning clearance without you having to get out of the truck and place the hitch into the maneuvering position each time. Since you already have the Turning Point on your trailer you'd

  • Recommended Air Bag Kit And Compressor For A 2019 GMC Denali HD 4WD SRW 3500
  • That is a nice setup. You are absolutely right that adding an air bag kit will help to reduce the porpoising and side-to-side movement while you are towing. When you factor in your campers hitch weight, plus the weight of your companion slider you should be just under/around 2,800 lbs added to the bed of your truck. For that reason we do recommend going with a Heavy Duty air bag kit. For that I recommend the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs # F2709. I prefer

  • Are There Adjustments You Can Make To A B&W Companion Slider For A Smoother Transition
  • There isn't anything you can really adjust for smoother sliding operation of your B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W, but you can wipe down the slider tubes with a damp rag and then spray on some dry silicone # RM-747 to lubricate the tubes without attracting dirt and debris, which is probably what is causing the bind that you're currently dealing with.

  • Front and Rear Clearance Dimension for B and W Companion Fifth Wheel Hitch BWRVK3500
  • From the center of the shank to each end of the base (forward and back) of the B&W Companion 5th Wheel Trailer Hitch # BWRVK3500 is 18 inches. So you would need to measure forward and back from the center of your gooseneck ball shank 18 inches to see if you have the clearance needed. We haven't had a chance to take this measurement in your truck bed so I can't tell you exactly what clearance you'd have like you asked about.
