Question:
I am looking at 5th Wheel to Gooseneck Pin Box adapters similar to GY57ND. Are the dimensions of these available somewhere. I saw one in the QandA section. I have a 2022 Forest River Sabre with an adapter I bought from you a few years ago on it part number CAB-C5GX1216. Based on the drawing I saw you use C/L ball to the top left bolt as a reference and I would need of ~28 vertical and 25 back from the ball to bolt.

Hey Wesley welcome back. I do indeed have dimensions for the Gen-Y Nomad 5th Wheel to Gooseneck Pin Box item # GY57ND. I attached the complete specs below.
The C/L measurement is only 20.3" and to the back bolt is 29.08" on the Gen-Y Nomad item # GY57ND. This pin box is designed to replace a 1621,1116, 1716 pin box.
The Shocker 5th Wheel to Gooseneck Pinbox item # SHK23MR is going to be the closest option I have for your clearance needs. It's got a C/L measurement of 25" and to the back bolt is 27" from the center of the coupler.
The Shocker item # SHK23MR is designed to fit a Lippert 1621/0719 and Rhino Box.
What bolt pattern does your current pin box have?

I have a 2020 FB3931Montana. Great tracking & handles well on the highway. The ONLY issue I have is potentially tight corners and curbs. You MAY get into a curb, and you're going to reduce the distance on a front corner of your coach, side rail of your truck beware of reduce clarence. Although I haven't had any damage yet. Good luck torqueing !!
