Question:

Hi, I was looking into upgrading to a Reese goose box and was unsure of which Lippert pin box I have. It is on a 2023 keystone cougar 2700BH. Serial number S010088494 RPO 0010041572 Thanks!

Hey Jordan! Thank you for providing that sticker. You have a 1621 pin box so you need the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR.

Any big trips coming up with your Keystone Cougar?
