Flex Air Pin Box Recommendation for 2021 Keystone Cougar 368MBI

Question:

I have a 2021 Keystone Cougar 368MBI with a Lippert Road Armor Trailair pin box. There are no other identifying model numbers on the pin box but the chassis has a serial number tag in the hitch mount showing serial number S005910273, RPO - 0005459020, and LCI item number 736262. I would like to upgrade to a Curt Flex Air pin box but I am not certain which is the appropriate replacement. The current pin box is rated for 18,000 lbs so I think either the LC328492 or LC328484 box is correct, but I cannot find guidance either from Lippert or Keystone. What is the correct pin box for my rig?

With the LCI part number of 736262 that indicates you have a Lippert 1621 style pin box on your 2021 Keystone Cougar 368MBI. So for a Curt Flex Air pin box that has the same 18k GVWR and is correct fit you'd want the part # LC328492 and you'd be set.
