I spoke to my contact at Lippert and they were not able to reference the part "190772131" that you provided. What you will want to look for is a white barcode which is located on the passenger side of the mounting bracket for the pin box. This number should start with either a "028" or a "019". Once you can let me know what this number is I would then be able to verify the correct replacement Reese pin box.

Thanks for the additional info! Based on this, the 5th Airborne Premium Fifth Wheel Air Ride Coupler part # 5AB-E1621-16K that you referenced will fit your RV. As I am sure you already know, this pin box has an integrated airbag which will work to reduce chucking by nearly 60%, decrease vertical shock by 44%, and reducing vibration inside the coach which will also in turn relieve stress on the frame. Please note that that if sitting idle for more than a week, the air springs should be drained to relieve pressure on the system. I have attached a review and installation video on this pin box for you as well.
