Our 2019 Reflection 303RLS has a two-door fridge. The Dometic recommendation for the RM1350 is for TWO ventilation fans. Ours has FOUR and they seem to block any cooling convection when the fans aren't running. I found this out when our limit switch failed and these fans never ran - the freezer and fridge would initially cool down, but then the fridge would warm back up to almost 60F. Maybe TWO fans would work if they were located in the right places. Just a thought.
