Fifth-Wheel Towing with Your Gooseneck Hitch

There are a variety of adapters on the market that let you tow a fifth-wheel trailer with a gooseneck hitch. You can use a coupler adapter that replaces the pin box on your fifth-wheel trailer and then attaches to the gooseneck hitch in your truck bed. But these adapters often require modifications to your trailer that can void the warranty. Another option would be using fifth-wheel rails that mount directly to your gooseneck hitch, usually by dropping into the hitch's ball hole. But to do this you have to make 2 separate purchases - the adapter plate that has the rails and a standard fifth-wheel hitch.

With the Companion Flatbed from B&W, you get a heavy-duty fifth-wheel trailer hitch that mounts in your flatbed truck by connecting directly to your Turnoverball gooseneck hitch with the included components. No modifications are required to your truck or trailer. And no additional parts are required for the system to work.

Quiet, Secure Ride

The 1" thick jaw on the Companion Flatbed 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 Base with 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 Flatbed 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".

Installation of the B&W Companion Flatbed

To install the Companion Flatbed, first bolt the hitch base together and then mount the arms to the base. Then position the base so that the post on the bottom inserts into your Turnoverball hitch's ball hole (in place of the hitch ball). Secure the post using the handle of the Turnoverball, just as you would secure the hitch ball. The post is square like the base of your gooseneck hitch ball. This square design helps to eliminate any twisting or turning of the post - and therefore the mounted fifth-wheel hitch - in your gooseneck hitch.

To tighten the connection between your Turnoverball hitch and the Companion Flatbed, torque down the integrated drop-down bolt. This bolt runs through the crossmember of the Companion base and then down through the post. When you tighten the drop-down bolt, the base will be pulled closer to your truck bed, creating a more substantial connection. This, along with the square design of the post, helps to ensure maximum stability when you're towing.

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.

Quickly and easily convert your B&W Turnoverball gooseneck hitch (BWGNRK1500 - sold separately) to a sturdy 5th-wheel trailer hitch for your flatbed truck. Dual-jaw hitch removes without a trace for full bed access.


Hitch is great, B&W products are exceptional. Had the turnover ball mounted on a Douglass flatbed. Purchased the fifth wheel hitch for a 37 ft two axle toy hauler. Pulls great, easy installation. Make sure to make all the appropriate measurements before purchasing. There were some shipping issues. etrailer failed to send a bolt bag initially. Took a while to get that rectified, but all is well.


I am very impressed with the quality of this BW 5th wheel hitch. I chose it because it what is recommended for use on my new flatbed for my truck. The flatbed is designed with this hitch in mind. It fits perfectly in the gooseneck well and is easy to install/remove. Just tighten/loosen the tension bolt and slide the locking pin to switch from gooseneck ball to 5th wheel.

Going with this hitch and a flatbed makes trailering so much easier. No more step ladders, standing on running boards or tire to reach the hitch handle. Just reach over, grab the handle to open/close the jaws and set the safety pin.

Highly recommend it.



My B&W hitch is still working great and Im very happy with my purchase.


Nice little hitch...but only if you have a flatbed. Was told by etrailer that this would work ok in my 2006 dodge ram pickup with factory bed. I can pull my camper with it, but only on perfectly flat ground. Was also told by etrailer this height was adjustable, but in fact it is not. I'm now looking for a used base that is the proper one for my truck. I also noticed etrailer scrubbed all their reviews and photos showing this sitting in the bed of a regular pickup and has since changed the description for only for flatbeds. I applaud them for doing this, just wish they'd done it before I bought mine. So if you have a flatbed, this is a great hitch. If you're thinking of putting it in the bed of a pickup, then get the RP3500 version of this hitch instead.

I have looked more into this hitch adapter, and this adapter height is not adjustable. I apologize for the misinformation. If you are wanting an adjustable adapter, I recommend part # BWRVK3400. This adapter has a GTW of 20,000 lbs.


What a great hitch ! I had purchased a 5th wheel RV about three weeks ago and thought without a doubt that I would be drilling holes in flatbed and be paying 1500 to 1800 to have a hitch installed.
Thanks to B&W I was able to install this hitch in less than an hour with no other expense other that the hitch itself.
Our first trip cover about 400 miles the hitch had absolutely no slack or play in towing. A great product . Precision made in the USA, Thank you !!


Finally found someone that was knowledgeable and could solve our towing needs after we had a flatbed installed on our truck!! Works great and received our order a lot earlier than estimated!


This was a perfect fit for my truck. I had no other (easy) way to hook up our fifth-wheel and this did the trick. Very easy to take out and is a very good quality hitch.


Excellent to deal, great prices, very helpful staff, could not have done any more to help & fast delivery. The only negative is that you cannot use a MasterCard with an overseas address attached to it even though you have a US delivery address & PayPal charges 3.5% plus the currency exchange rate.



Hitch is working fine, easy to set up & remove when not in use


The bolts hit the side oh the throughway on an Cm/ER model bed etrailers was no help at all.

This is just an adapter, so there is no guarantee that it will fit your application. What I can do is send your information over to our customer service department for them to set up a return for you and look into some other possible options for your CM ER model bed.


Works perfectly.


Outstanding price of equipment


BW nailed this one!!!...the flatbed companion 5th wheel it's top notch...built to last....and you don't need to be a welder/ figure this and finish is #1....i looked at goosneck adp for the serv mgr brad in Tucson said he has had 15 5th wheel trailers with broken frames ..( from using goose neck adp on there 5th wheel trailers) i looked at the air ride goose neck stinkin much$$....then i saw the flatbed companion by bw...boom!!...price....nice...2 min the unit is off and i have my full flatbed to use as i have always used...nice....if your a guy like me who has a truck to be used as a truck..( not a walmart runner) .this my friend is a no brainier......they also make them for pick up beds....


This is the second unit I have owned. The first in a Ford and the second for a Chevy. Easy to assemble and install. Great directions. It fits in the B&W Gooseneck receiver, latch the latch, then connect the floor safety bars, tighten and torque the bolts. It tows great!! Heavy to get into the truck, but comes in two pieces. The base mounts first then the top section sit on the rocker bearings and latches. Can't beat buying from etrailer!!


This product is just what the doctor ordered. The instruction sheets are good, and show the manufacturer spent a goodly amount of time getting them just right. I would recommend this hitch to anyone with a flatbed, having a turnover ball installed, get this hitch. it is easy and fast to install and the cost is just right.


Great build quality. This is the only fifth wheel hitch I could find to fit the tight space on my truck.


Exactly what I ordered came in exactly when etrailer said it would. Good service!



Hands down best towing purchase I ever made.


Awesome website. Have ordered from them before and great prices and fast delivery!


A good hitch if you have a flat bed but it does not work with a recessed pin box


Awesome staff! Great turnaround time. Thank you ! We will be installing our hitch today to head out soon!


Works great with our toyhauler


Great all around with customer support through videos, emails and phone conversations giving great descriptions and how to information. Price was the best that I could find. Thanks etrailer.


Great service from e-trailer and a great product.


Hitch works perfectly. Easy in and out when I need the whole truck bed. Awesome product.


Great Product and as always fast shipping. Install went fast and easy highly recommended.


Excellent customer service, great lead times and accurate shipping times!
