Hey Brad, thanks for reaching out!
What pin box number do you currently have installed on your 2021 Grand Design Reflection 31MB? You should find a sticker with a number like "1621" or even a serial number and the brand would work.
Not all 5th wheel trailers come with the same pin box but once I have the info listed above I'll be able to help you find the correct Gen-Y gooseneck coupler.
For example, the Gen-Y Hitch 5th Wheel to Gooseneck Pin Box # GY38FR will replace a 1621 or 1621HD pin box and is in the weight range of your 5th wheel.
