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…
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…

5th Wheel Gooseneck Adapter that Replaces Pin Box
Swap your fifth-wheel hitch for a clean bed and tow on your gooseneck ball. This 5th wheel gooseneck adapter replaces pin box to bolt up where the original came off, keeping the hookup simple. For short beds or tailgate clearance, consider an offset design or use an offset gooseneck ball, and match to your current pin box number or bolt pattern for compatibility.
Short-bed setups typically benefit from offset. Some adapters provide a 3" offset; others have no built-in offset and rely on an offset gooseneck ball. One setup needed a 4" offset ball to open the tailgate while hitched. Measure cab-to-ball distance and your trailer's nose width to confirm turning and tailgate clearance.
Match the bolt pattern on your trailer's pin box. Adapters are offered for common patterns like 1621, 116, and 1716, and install using the same bolt locations as the old pin box. Check the sticker or serial number on your current pin box to verify. Set the adapter in the bed, couple to the ball, and use a jack to fine-tune height for bolt alignment.
You can see reduced chucking and better damping, but results vary by setup. One setup was a night and day improvement with rhythmic chucking gone, while another saw little improvement on the first trip. MORryde GooseTech uses a rubber spring that dampens shock with 3" of fore/aft travel and no real vertical movement. Recheck height and clearances if you feel excessive chucking.
Install usually takes about an hour and uses the old bolt locations. Support the adapter with a jack, start a few bolts per side, then finish tightening. Some kits don't include new hardware, so be ready to reuse bolts and inspect mounting plates for alignment as you torque them. GooseTech uses a Demco eZ-Latch; use an InfiniteRule lock for cast Demco eZ-Latch couplers. Safety chains are required on GooseTech.
