Switching from a bulky fifth wheel hitch to haul cargo leaves you lifting heavy hardware out of your bed. This pin box converts a Lippert Rhino trailer to a gooseneck with dual axis cushioning, so you can tow smoother and keep your bed clear.


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.

  • 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&W 5th Wheel to Gooseneck Pin Box Fit 2020 Vanleigh Beacon 34RLB
    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. If you have an 1116 or 1716 you need the # BW83RV with the shim kit # BW57MV. If you have the Lippert Rhino Box on there now you need # BW55RV instead. If you aren't sure which bolt...

  • How to Determine Clearance Using B&W Gooseneck Pin Box With 2009 Ram 3500 Short Bed
    Hey Fred! You will need to take some measurements to determine if you will have enough clearance with the B&W Gooseneck Pin Box # BW23RV. 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. You can also live with the lost clearance as long as you know your limitations....

    Hey Dean! The B&W 5th Wheel to Gooseneck Pin Box # BW73RV will fit your Brinkley Z2900 if you have a Lippert 1621/1621HD bolt pattern. Also yes, there is a heftier model, which is the # BW83RV with a max tongue weight (TW) of 4,500 lbs. What is your pin weight with the generator? As long as you aren't over that 4.5k limit you're good. If you have an 1116/1716 you will need the 1621 pin box along with the Shim Kit for B&W 5th Wheel-to-Gooseneck Pin Box # BW57MV.

  • Will B&W Gooseneck Pin Box Work With 2025 Forest River Riverstone Legacy 39RKFB
    Hey Jim! Yes, the B&W Gooseneck Pin Box can be used on your 2025 Riverstone 39RKFB. However, you need to determine the pin box bolt pattern to find the right model. The # BW83RV you were looking at is designed for a Lippert 1621/1621HD bolt pattern (also fits 1116/1716 with shim kit # BW57MV). If you have the Rhino Box you need # BW55RV instead. If you aren't sure which bolt pattern is on your 5th wheel, feel free to send me a picture of the pin box sticker and I will identify it for...

  • Does B&W 5th Wheel to Gooseneck Pin Box Include Safety Chains
    Hey Shawn! Yes, the B&W 5th Wheel to Gooseneck Pin Box # BW23RV does include safety chains. That is one of the first things we asked them when they came by to show us the new pin box. They also throw in replacement hardware so you're covered if you need it. Gooseneck pin boxes are already pricey, and it can be easy to forget the safety chains, so it is nice that B&W decided to include them. This particular model is designed to fit a Lippert Rhino bolt pattern so make sure that is what...

  • B&W Gooseneck Pin Box for 2025 Alliance Avenue 32RLS With 2026 Ram 3500 Dually
    Hey Paul! The correct B&W Gooseneck Pin Box depends on your pin box bolt pattern. If your 2025 Alliance Avenue 32RLS has a Rhino Box you need # BW23RV and if it is a 1621/1621HD # BW73RV. 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?

  • 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 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...

  • Will the B&W 5th Wheel to Gooseneck Pin Box Work w/a CM ER Flatbed Trough?
    It sure is Tyler! The B&W 5th Wheel to Gooseneck Pin Box item # BW83RV is indeed compatible with the gooseneck trough on CM ER flatbeds. The gooseneck connection point is more narrow to prevent the latch assembly from striking the flatbed during turns. You'll have plenty of clearance. I attached a picture below so you can see how the connection point is noticeably more narrow to allow for turning clearance.

  • Will B and W Fifth Wheel to Gooseneck Adapter Void Lippert Warranty
    Hey Danny, this is a really great question but B and W states that their fifth wheel to gooseneck adapters like the part # BW83RV actually put less stress on the RV frame than a pin box so the warranty would not be affected. Lippert might take a different stance but they have allowed the Goose Box to not void the warranty which is very similar. What RV do you have?

  • Will B&W Gooseneck Pin Box Reduce Chucking On 2026 Montana High Country 290RL
    Hey Vern, welcome back! The B&W Gooseneck Pin Box # BW83RV will definitely reduce chucking and smooth out your ride. Kevin from our installation and review video installed this on his Jayco and said there was a noticeable improvement while towing. Others have reported the same. It is also one less thing to deal with since you're removing the Andersen from the equation. We have actually seen a lot of people upgrading to the B&W from the Curt Helux.

  • Is There a Way to Lock the B and W Fifth Wheel to Gooseneck Adapter
    Hey Ben, welcome back! Unfortunately, there isn't a great locking solution for the B&W 5th Wheel to Gooseneck Pin Box # BW83RV. Standard gooseneck coupler locks won't fit this setup, and when we spoke with B&W they didn't have plans for a more extensive lock at this time. For now, your best option is to run a standard padlock through the hole in the coupler latch. I know it isn't the most robust solution, but it will at least keep the latch from being opened and provide some theft deterrence.

It mounts to your gooseneck ball and comes with a MOLLE panel for your Chevy so you can fold up the hitch and store it at the front of the bed when you're not towing.
