I spoke to Lippert who confirmed your Grand Design Reflection 303RLS uses a Lippert 1621 Pin Box. There, the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box part # GY58GR which is what I recommend using is a fit. Unlike the Reese Goose Box, the Gen-Y uses a rubber spring so there's no maintenance.
