Will The B&W 5th Wheel to Gooseneck Pin Box BW23RV Work With A 4" Offset Gooseneck Ball?

Updated 05/11/2026 | Published 04/28/2026

Question:

Would this be compatible with a 2026 Alliance 37V11 connected to a 4inch offset BandW turnover ball in a 64inch bed?

Hi Jim!

As long as your 2026 Alliance Valor 37V11 has the Lippert Rhino box currently, the B&W 5th Wheel to Gooseneck Pin Box - Lippert Rhino - 25K GTW - 3.25K TW # BW23RV will indeed fit. If you have a different pin box, just let me know and I can see if we have a different option for you.

This will also have no issues working with an offset ball. B&W was actually at our facility a couple weeks ago and we asked them about just that kind of thing. They said there would be no problem using an offset ball in the short bed trucks.

That's one heck of a camper as well! What are you towing it with?

Thank you for the info. Im currently towing with a 2025 Ram 3500 standard bed with Rambox. Will the Rambox be an issue?

@Jim Sorry for the delay. I just heard back from B&W and they do not recommend using this system with the RamBoxes. The width of the bed is not enough to accommodate the bulk of this adapter, unfortunately. With the RamBoxes, you will need to stick with a fixed 5th wheel hitch and a rotating pin box. Sorry I don't have better new for you. : (
