Hey John, the Reese Goose Box part # RP85FR is correct for your 2023 Keystone Cougar Half Ton as we know it has a Lippert 1621 pin box.

Hey John, did the Reese Goose Box work well with your Keystone Cougar? I'd love to hear how it turned out, as it could give others confidence when ordering replacements.

@JamesonC Installed today. Was challenging as it required a slight modification to the pin box. I believe the angle underneath the pin box was over bent causing the goose box to be unable to line up holes. We had to notch out very Small areas (1/8”) on each side of the angle. Once we did that it bolted right up. 6 bolts. It is perfectly level and has good clearance all around. Hats off to 62 Sales for the install.
