Hi Dominic; thank you for providing that info and the picture. Your current pin box uses a 1621 bolt pattern. With a 14k GVWR and the Gen-Y formula GVWR x 0.22 = TW you need the 4.5k TW model as you said. These two pieces of information are all that are required to choose the right pin box. The correct pin box for your 2022 Grand Design Reflection is the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY38FR.
