The number you found on the pin box of your 2014 Dutchmen Denali appears to be the VIN for the trailer. I called and spoke with my contact at Dutchmen to see if they could provide any identifiable information on the pin box using this number and the only thing they could verify was that it is a Lippert pin box. They went through some changes in 2014 so unfortunately they were not able to track down the actual pin box model number.

I recommend first checking the pin box once more for any stickers or numbers that might be printed anywhere on the unit that refers to the pin box model. If you are unable to locate any other information, then your best bet is to take a few measurements to determine the model. I have attached an article that explains exactly how to do this so that you can verify the pin box number and in turn the replacement pin boxes that will work in its place.

The Trailair Flex Air 5th Wheel Pin Box # LC328492 that you are looking at is designed to replace the Lippert 1621 pin box. I have attached a couple images that refer to the measurements you will take on your pin box. If you do in fact have the Lippert 1621 pin box, the measurements will be as follows:

2a = 7-7/8 inches, 2b = 2 inches, 2d = 5/8 inch, 2e = 15/16 inch, 2f = 6 inches, 3a = 17-3/4 inches, 3b = 25-5/8 inches, 3c = 12 inches.
