Hi Charles, based on the information you provided, you may have a Lippert 1621 series pin box, but I can’t confirm that for sure from the LCI 2020221615 and RPO 0012249009 numbers alone. We don’t carry the Reese Goose Box, but I can reach out to Lippert to see if they can identify the pin box used on your 2024 Keystone Cougar 316RLS and help narrow down the correct fit.

Does your pin box have a sticker or label on it? If so, a photo of that label and the pin box itself would be really helpful.
