My 2019 Rockwood came with this fridge door clip things. At first, I didn't know what the heck they were!
But, since they were in the fridge when I found them, figured they were for it
Played around with them and figured out they fit this way.
So, here is how they work. The leave a gap in the door and so far as worked great.
On my old Prowler, I just left the doors open or used a dish towel on the door to keep them cracked at least...
No idea where you can get these... Like I said, they were just inside the fridge on my brand new Rockwood... :) Love 'em!
