Expert Reply:
Hey Rick, since we know your 2018 Keystone Fusion 424 has a Lippert 1621 style pin box on it currently the correct Gen-Y fifth wheel to gooseneck adapter would be the part # GY38FR.
Or if you were wanting a Reese Goose Box instead you'd want the part # RP85FR.
If you want an air spring the Goose Box is the correct route, if you'd prefer a rubber torsion spring for cushioning you'd want the Gen-Y. Worth mentioning is that the Goose Box is technically only option that doesn't void warranty.
