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.

  • Does the B&W 5th Wheel to Gooseneck Pin Box Come w/ Safety Chains?
    It sure will Shawn. The B&W 5th Wheel to Gooseneck Pin Box item # BW73RV does indeed come with the required safety chains. This pin box is designed to replace a Lippert 1621, 1621HD, 0719, Fabex PB 600 Series pin box. There will be a shim kit that allows it to replace a Lippert 1716 pin box as well. What model pin box does your 5th wheel trailer currently have? You can add this information, along with any other questions you have, where it says Add Comment. Please note that if you...

  • 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...

  • 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 options 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 the Lippert Rhino Box on there now you need # BW55RV instead. If you aren't sure which bolt pattern you have, feel free to send me a picture of the pin box sticker with the...

  • Is there a B&W 5th Wheel to Gooseneck Pin Box for a 1716 Bolt Pattern?
    Yes, they do Brad! The B&W 5th Wheel to Gooseneck Pin Box item # BW73RV is the correct one you'll need to replace your MORryde Cushioned 5th Wheel Pin Box item # MR97VR. There is an additional shim kit you will need to adapt the B&W 5th Wheel to Gooseneck Pin Box item # BW73RV to work with your 5th wheel trailer's Lippert 1716 bracket. However, it will not be released until the end of May beginning of June according to my contact at B&W. This is the same timeline for the release of the...

  • 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...
