Question:
I have a Brinkley Z2900. Will this mount to my unit? Also I have a preinstalled Cummins generator, which adds to my pin weight. Will this still work or are you coming out with a heftier one?

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.
If you have a Rhino Box on the Z2900 you need # BW23RV (3.25k TW) or # BW55RV (4.5k TW) instead. If you aren't sure what bolt pattern is on your pin box, feel free to send me a picture of your pin box sticker and I will identify it for you.
Any big trips coming up with the Brinkley once you swap out your pin box?
