Ammonia Fridges, read an interesting piece a while ago

The only “temp differential or delta” that I see is between the fridge and freezer temps....usually 30 degrees. Even when it’s 115 ambient and the trailer is 98 inside, my freezer is 3 and my fridge is ~33

Dometic rm2652 with 2 external fans, triple internal fans and Amish cooling unit......oh yeah dinosaur board and variable thermistor adjustment box.

I do get a little overcooling at night sometimes camping when ambient drops to 45 and my fridge gets to 29....just twist the adjust knob.
