Switching from a bulky fifth wheel hitch to haul cargo often requires removing heavy hardware from your bed. This pin box converts your trailer to a gooseneck, reducing in-bed equipment while adding dual-axis cushioning for smoother towing.


Highlights

  • Open Bed Between Trips: Gooseneck connection removes bulky in-bed hitch hardware from cargo runs.
  • Controlled Towing Motion: Dual-axis cushioning absorbs up-and-down and front-to-back movement.
  • Road Shock Dampening: SumoSprings suspension manages road shock across rough pavement.
  • Ball Hookup Alignment: Large funnel design gives the coupler a broad target at the gooseneck ball.
  • One-Pull Coupler Release: Easy-reach latch cable releases the coupler from an accessible position.
  • Immediate Towing Setup: Maintenance-free spring system needs no break-in period before towing.

Features to know about

Open Bed Space Between Towing Trips

Hauling cargo between trips gets old fast when a large fifth wheel hitch takes up your bed. This pin box converts compatible fifth wheel trailers to a gooseneck connection, moving the towing point to a single ball connection. Your bed stays open for cargo runs once the bulky in-bed hitch is out of the way.

Controlled Motion on Rough Roads

Long towing days can send vertical bounce and front-to-back movement through your trailer connection. Dual-axis cushioning absorbs up-and-down and front-to-back movement during travel. The trailer connection keeps motion controlled as the road surface changes.

Road Shock Dampening Underway

Rough pavement can send sharp jolts through a rigid towing setup. SumoSprings suspension creates dynamic dampening over rough roads, giving road shock a place to compress through the connection. The trailer keeps tracking through uneven pavement with less harsh feedback at the hitch point.

Gooseneck Ball Hookup Control

Hooking up a gooseneck takes careful positioning when the coupler target is small. Large funnel design gives the coupler a wider lead-in area as your trailer settles onto the ball. Coupling lines up with a broader target, and the easy-reach latch cable releases the coupler from an accessible position.

Everything was perfect!

I waited for a couple weeks to get a good perspective with the new hitch. After driving I 40 through New Mexico and several states I can honestly say this is my best hitch in 22 years of experience towing. Some chucking still happens but diminish by at least 75%. F-350 towing a Momentum 320 fully loaded with 2 Harley’s.

I installed the BW 73RV pin box and I am impressed. It is a very sturdy unit and was easy to install and adjust. I like that the chains have safety hooks on both ends so you can hook to the truck first and don't have to crawl in the bed to hook up chains after connecting the fifth wheel. I did have to buy a good padlock to secure the hitch since a standard gooseneck lock will not fit. It would be nice if B&W made a good theft deterrent lock for this pinbox. I have only driven a short distance with the hitch but it seems very smooth. We have a trip coming up and I'm excited to see how it does

We are going to head toward The Moryde facility in Elkhart Indiana to have the independent suspension with hydraulic disc brakes installed on August 3rd. We are making a cross country trip out of it we are going to Theador Roosevelt National park, Two Harbors Michigan, the ark encounter in Kentucky, visiting family in Tennessee, then headed down to New Orleans, that making our way back to Idaho through Albuquerque New Mexico and Durango Colorado.

@Russell Oh wow, that is awesome. Disc brakes is one of the best upgrades out there for stopping power. You have quite the trip planned, New Orleans is my FAVORITE. Are you visiting Lafitte's Blacksmith Shop?

  • Which B&W Fifth Wheel to Gooseneck Adapter Is Best For Towing My Trailer?
    Hi Glen, It will depend on what the GVWR (gross vehicle weight rating) is of your trailer to determine which B&W 5th wheel to gooseneck adapter will work best for you. Fifth wheels and gooseneck trailers go off of pin weight instead of tongue weight like a bumper pull trailer uses. Pin weight is 15-25% of your trailer's GVWR, typically we use the formula GVWR x 0.22 to give us a median pin weight number. For example, if the weight of a fifth wheel is 18,000lbs GVWR then we do 18,000 x...

  • Which B&W 5th Wheel to Gooseneck Pin Box For A 2023 Forest River Sabre 37FLL?
    Hi Sonny, cool camper! The B&W 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621HD - 25K GTW - 3.25K TW # BW73RV will be a great choice! With your 2023 Forest River Sabre 37FLL having a 2,600 pound pin weight, this one will be the better option (the # BW83RV has a much higher pin weight capacity of 4,500 pounds and would end up being pretty rough). You can also use a 4" offset ball with these as well. That's no problem at all. If you don't already have one of those, I will need to know...

  • Will B and W Fifth Wheel to Gooseneck Adapter Void Lippert Frame Warranty
    Hey John, this is a great question. I asked B and W about whether or not the B and W Fifth Wheel to Gooseneck adapter part # BW73RV would void the frame warranty and they said it has been extensively tested and engineered to provide a smooth, stable ride that helps reduce stress on both the truck and trailer. Use of the adapter should not void your trailer's frame warranty. What fifth wheel camper do you have?

  • Availability of a B&W 5th Wheel to Gooseneck Pin Box for a Turning Point Kingpin
    Thanks for reaching out, Weston! At this time we are unsure of all the different compatibilities that B&W will have. These just came out on the market less than a month ago. I would imagine as the demand grows for other fitments, they will make more compatible pin boxes.

  • What B&W 5th Wheel to Gooseneck Pin Box Do I Need For A KZ D326RLT?
    Hey Donald, thanks for reaching out. We will definitely have a gooseneck pin box for you, but they aren't make and model specific, so there is no way to look up the camper and know exactly which one you'll need. Specifically, we need to determine what pin box size/bolt pattern the camper was equipped with from the factory. The dealership might be able to tell you, otherwise, the only way to figure that out is by looking at the pin box and finding the sticker on the side. Every camper will...

    Hey Justin! Based on the pin weight and GVWR of your 2020 Vanleigh Beacon 34RLB you will want to get the 4.5k TW model. There are two different models depending on your bolt pattern. If you have a Lippert 1621, 1621HD, 0719, or Fabex PB 600 Series you need the B&W 5th Wheel to Gooseneck Pin Box # BW83RV.

  • Which B and W Fifth Wheel to Gooseneck Adapter for 2025 KZ Durango Gold 358RPQ
    Hey Russel, so fifth wheel pin weight is generally between 15 and 25 percent of the total weight of the trailer as it sits ready to tow. This is different than the GVWR that you mentioned as that number is the total amount the trailer can weigh at max. So most likely the part # BW73RV would be your best option as if you use 20 percent of the GVWR you end up at 3,000 lbs which is under max rating of the # BW73RV plus fact you are most likely not going to be at the very max your trailer can...

  • How Much Does The B&W 5th Wheel to Gooseneck Pin Box BW73RV Weigh?
    Hi David! The B&W 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621HD - 25K GTW - 3.25K TW # BW73RV weighs right at 175 pounds. It's beefy, but it's also very nice. As all B&W stuff is. This can be installed at home, but it's not easy and you will either need a forklift or a couple friends to hold it up while you put the bolts in place. What are you wanting to install this on?

  • Can I Use The B&W 5th Wheel To Gooseneck Pin Box With A RamBox Truck?
    Hello Daniel, Thanks for writing in. I am sorry but, no, I would not recommend using the B&W 5th Wheel to Gooseneck Pin Box # BW73RV with a Ram truck equipped with RamBox. The challenge with RamBox trucks is that the bed walls extend farther into the bed than a standard pickup, which reduces turning clearance between the trailer and the truck. To safely tow a fifth wheel with a RamBox truck, you need a rotating pin box that moves the pivot point rearward and away from the truck during...

If you aren't sure, please send me a picture of your pin box sticker and I will be able to identify it through Lippert. Both of these are the 3.25k TW models which is the proper rating for your Alliance Avenue. Where are you headed once you upgrade the pin box and get your new truck?

    Hey Dustin, the B&W 5th Wheel to Gooseneck Pin Box # BW73RV is a really great cushioned pin box adapter that will work well for your Grand Design.

You can use the following formula: (A + B) - C = Clearance A = Distance from the gooseneck ball center to the truck cab B = Offset used C = Width of the nose of the trailer divided by 2 As long as you have at least 4" of clearance you will be able to make a 90 degree turn.
