Hey Rudy,
There unfortunately isn't a guide to tell us how large the passthrough is on a 2025 Grand Design Reflection 303RLS so you would need to take a quick measurement. The MORryde RV Cargo sliding Trays are like a 1/4" smaller than their listing with the thought being that they would fit directly in the space they're listed as without issue so the # MR55FR you were looking at would fit with a 72" x 42" cargo space.

Hey Rudy, were you able to measure the passthrough on your Grand Design 303RLS to see if the MORryde cargo tray would fit? Once you had those dimensions, it should have been easier to confirm the right size. Your update could make it easier for the next person with the same setup.
