Thank you for the picture!

I reached out to my contact at Lippert and based on the serial number you provided I was able to confirm that your trailer has a 1621 pin box with an 18000lb rating.

For a gooseneck pin box that will fit you will need either the Reese Goose Box - 20000lb # RP85FR or the Gen-Y 25000lb # GY38FR.

Between these two options I recommend the Gen-Y # GY38FR due to it having a built in shock absorber feature that will give you a smoother ride, but also due to it having an auto latch coupler that allows for an easy hook up.

I included videos for both of the products mentioned for you to take a look at.
