Hey Travis, since your Grand Design Reflection 100 Series 28RL has a Lippert 1621 style pin box on it currently the correct Gen-Y fifth wheel to gooseneck adapter that is cushioned you'd need is the Gen-Y part # GY38FR. What gooseneck hitch do you have?

I went to the General Y manufacturer and got the proper dimensions. Then I ordered it to E Trailer. It worked great amazing upgrade on a fifth wheel.
