Replacing 5th Wheel 1716 Pin Box With Upgraded Cushioned Gooseneck On 2020 Grand Design Reflection
Updated 11/03/2025 | Published 10/29/2025
Question:
We tow a 2020 Grand Design Reflection 303RLS and from the spec sheet it shows a Lippert 1716 pin-box. We’re thinking of converting to a gooseneck for better bed-space - is the MR39MV the right MORryde GooseTech adapter for us?”

Lisa - you’re on the right track. For your Reflection 303RLS, if it indeed has the Lippert 1716 pin box, then the MORryde GooseTech model # MR39MV is made for that exact pin-box bolt-pattern. The 1716 is very common in that size trailer category.
Just double-check that your trailer’s GTW gross trailer weight and the pin-box label matches the 1716 rather than a different variant so you pick the correct adapter. This unit is rated for RVs between 11.5K to 14K GTW. Once confirmed, you’ll get the gooseneck hitch freedom (no bulky 5th wheel hitch anymore) and a more cushioned ride!
What truck bed and gooseneck hitch are you planning to use?

Thanks, Andrew! We’re towing with a 2021 Ford F-350 long bed that has the factory puck system and B&W ball. Is the install something we could do ourselves or should we take it to a shop?
