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".

Assembly of the B&W Companion

To install the Companion, first bolt the included RV post to the Companion's base. This post is what inserts into the hole in your truck bed. The RV post attaches to the base in 1 of 2 ways to allow for improved cab clearance and proper positioning over your truck's axle.

The next step is to set up the Companion's pivot arms. The 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 the cab clearance needed to execute turns while towing.

Companion 3500 Base Diagram

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 above diagram gives an indication of where to mount the arms so that you get the height and the cab clearance that you need.

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.

  • Use your truck bed for things other than just towing and need to be able to remove the hitch
  • Just bought a new fifth wheel, but you have a horse trailer with a gooseneck too and want to be able to use the same truck to tow them

No, if you:

  • Have a rotating pin box like a Sidewinder on that new fifth wheel

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 3-1/2" 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.

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).

This part of the installation is easy. There are two main pieces. Fasten runners on the bottom of each of the two legs that sit in the bed grooves. Attach the large square pin that goes in the hole in the bed to the main base(there are several bolting patterns depending on where you want the 5th wheel assembly to sit in the bed) and set it in place. Item is heavy even without the upper part (5th wheel plate assembly). Best done by two people. 5th wheel plate assembly also heavy, but can be handled by one person. The directions are clear, easy to understand. Very nice clean setup.

Product has worked fine. Ive towed over 5,000 miles with it this year and have had absolutely no problems with the hitch what so ever.

The construction of this hitch is very heavy duty. The reason I gave this a low rating was due to the condition it was in when it arrived. There were parts missing. One of the handles that releases the upper hitch from the base was bent. There were numerous chips and deep scratches in the paint. For the amount of money I spent on this hitch I expected it to be brand new and undamaged. I sent emails with pictures to etrailer, they were supposed to issue me a credit but I never heard back from them.

I will have our Customer Service team reach out to you.

Build quality was great and it looks perfect. My only issue is they should supply hard washers and better quality lock washers. 2 of them bent so bad I had to remove them and file the heads to get the huge burrs off to tru to seat another one. If you supply high strength bolts you need to supply a higher grade lock washer it it just tears up the power coat .

Still working great

I haven’t pull the 5th wheeler yet, but the B&W Companion is a super heavy duty hitch and it looks like it will handle the job. The installation of the hitch went well. The instructions were pretty straight forward. No problems.

Prior to the Companion hitch I now have in my 2018 Ram I had a Patriot hitch for my 2003 Ram. Both hitches have preformed without question. I could not be more satisfied with the performance of either of these top of the line hitches, from their install to the solid locking of the hitch when it is engaged to the camper. I travel with insurance that my trailer will be with me when I get to my destination.

Great 5th wheel trailer hitch, the only negative was the lack of installation documentation. We had to go online to find the step-by-step instruction, would have been nice if it came with the hardware

Just finished installing my B&W Companion 5th Wheel hitch. I hooked to my RV to check my instillation, everything went very smooth. I would recommend this hitch to anyone with a Gooseneck turnover ball B&W hitch installed in there truck bed. Great product, very easy instillation.

This hitch is working out great. Easy to take out and put in. Two of my friends have purchased this hitch after seeing how great they work. Love my hitch!

Great hitch!Worked out great nice that BW has such good quality control ,it fit better than you could hope for.Only thing I did was drill the 3 1/2 " hole the placed the hitch upside down in the hole ,squared it in the box the marked the 4 safety chain u-bolt holes with a 9/16 " bit ,this gave me the centres of the holes then drilled pilot holes then the 9/16 " holes all from the top in the box.I found that much easier and this worker perfect.Will use again for sure.Keep up the good work.

I have had 4 different hitches and this hitch is buy far the best

Received my companion hitch in two days. Free delivery. Couldn’t believe how fast it shipped. I installed it myself in 3 hours. The hitch is rock solid and built heavy. I can’t wait to hook on to my camper and try it out. It is very easy to install. A second person would be useful to set base.

I installed this directly after installing the underbed turnoverball gooseneck hitch, and it was an easy install. Very well written instructions. Equipment looks robust, top notch welds, nice thick powder coat.

Great product. Works flawlessly.

We received our new BW Companion hitch on time. Noticed that our BW Turnover Ball hitch already installed in truck required a shorter socket post one week out from our trip. With a quick discussion with the great people at etrailer as well as BW, we had the new socket post shipped and installed prior to leaving town. Easy install - All worked as designed. So glad to have responsive parties involved here to help us out. Thanks!

I recently bought the gooseneck and fifth wheel b&w hitches to install on my 2008 f 250. I could not be more happy with the products and customer service that etrailer provides. I also bought The Pollack t connector that was also easy to use. The install was done at home and easy to understand. Thanks again.

This is my third B&W companion 5th wheel hitch. The first two were the old version. I like the updates they have made too the unit making it stronger and the narrower base. My only complaint is with UPS shipping which tore up the shipping box and dumped it on my driveway without even notifying me, luckily the hitch wasn't damaged and nothing missing.

I would like to say that I was not looking forward to putting this hitch on my truck. I heard nothing but nightmares and horror stories, but it couldn't be farther from the truth. I had a friend come over to help (glad I did cause that turnoverball hitch would have been a bear to hold up by yourself. It was ten times easier than I would have imagined. Just follow the instructions and it's a piece of cake. We had the turnover all hitch on in less than 2 hours. Unfortunately I had a rusted brake line that I had to repair before completing the job. Haven't used it yet but can't wait to hitch it up and hit the road. Thanks for making this hitch so easy to install. I'm glad it's American made and extremely heavy duty.

I like everything about this coupler. It works well. The only improvement that could be made is if it would lock when you back into it.
