If you have no identifiers on your 2016 Keystone Cougar 333MKS then the only way to determine the bolt pattern of your pin box is to either contact the manufacturer with the frame number, which is usually extremely time consuming, or to use our guide which will have you take a few measurements and plug those measurements into a spreadsheet. Attached below you will find our help article titled "4 Steps to Choosing Your 5th Wheel Pin Box".
Step 1 will have you determine the style.
Step 2 will have you take some measurements.
Step 3 will have you take those measurements and match them up a pattern in the spreadsheet.
Step 4 is just choosing the correct replacement after learning what your bolt pattern is.
For example, the most common bolt pattern is the 1621. If you had this bolt pattern you could replace your current pin box with the Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000lbs # LC328492, which has an internal air bag and built-in strut to work with the rubberized pivoting head to achieve a dramatically smoother ride.
