B&W Gooseneck Pin Box for 2026 Alliance Avenue 25RL

Updated 09/25/2026 | Published 09/24/2026

Question:

I have a 2024 Silverado 2500 Duramax crew cab short bed with a BMW flip ball hitch being installed next week. It will have a 4 inch extension offset towards the rear as an option.. I’ve also purchased an 2026Alliance Avenue All-access 25 RL that uses the Lippert/Rhino pin box what ive been told by dealer. I believe this is the correct model since the pin weight is 1,350 pounds and the GVWR is just under 11,000 pounds. Going to have the dealer install, but not sure if I will purchase and shipped to them or if they will want to purchase, and control…

Dave, the B&W 5th Wheel to Gooseneck Pin Box for Lippert Rhino, part # BW23RV, is the correct option if your 2026 Alliance Avenue 25RL is equipped with the Lippert Rhino pin box you were told it has. The 25RL is listed with a 10,995 lb GVWR and 1,350 lb hitch weight, and the # BW23RV is rated for trailers up to 25,000 lbs with a 3,250 lb maximum tongue weight, so the capacity is more than sufficient for your trailer.

This pin box replaces the fifth wheel pin box and converts the trailer to a gooseneck connection, so you can use the B&W gooseneck ball in your Silverado instead of having to install and remove a bulky fifth wheel hitch. It also uses a shock absorbing design to help reduce the road shock and chucking that can come through the connection.

The one thing I would have the dealer confirm before ordering is that your specific trailer actually has the Lippert Rhino pin box. Alliance's current information for the 2026 Avenue All Access lists the 25RL, but the published information I found does not confirm the Rhino pin box specifically, so I would want that checked before you have the dealer install it. Once they confirm that, the # BW23RV is the B&W adapter I would use for this setup.

here do you plan to camp, tight state parks or wide open sites?
