Reese Goose Box For a 2022 Keystone Alpine 3910RK 5TH Wheel Camper
Updated 02/23/2023 | Published 02/22/2023
Question:
I have a 2022 keystone alpine 3910RK. I want to add a goosebox 20k to my unit. I do not see a model on my king pin box. I did the measurements from your site and they are as follows on my unit. What model goosebox do I need or is there adapter plates to existing models that allow one to work? 2a.- 8” 2b.- 6” but that seems wrong. The first hole is at the top against the bend. But if I measure from the inside down to the first hole it is 6” 2d.- 1” between each hole 2e.- 7/8” 2f.- 5 on each side 3a.- 17” 3b.- 25” 3c.- 12.5” outside to outside

I was able to contact Lippert who identified you have the 1621 pin box on your 2022 Keystone Alpine 3910RK 5TH Wheel Camper. This will require the Reese Goose Box # RP85FR.
