Hi Gary, I completely understand wanting to get this right the first time because the last thing you want is something that doesn’t bolt up correctly or leaves you second guessing your setup on the road.
For a 2026 Grand Design Reflection 337RLS, that trailer almost always comes with a Lippert 1621 pin box, so you’ll want a MORryde GooseTech that’s built for the 1621 pattern with the same weight capacity as the Reflection which is part # MR97MV.
What do you most enjoy using the 337RLS for, long trips, weekends, or more off grid style camping?

We are snowbirds from Canada and spend 4-6 months travelling the southern states. Hopefully down to Baja one day.
