Adding fan behind refrigerator...worthwhile??
I have 3 RVs and I seem to be addicted to adding stuff to them....lol. They each have a standard Dometic 2852 absorption refrigerator. They seem to be working as expected. I did replace the cooling...

I would like to understand better what the NORMALtemps are behind the refrigerator while in operation. I assume it is somewhat (or heavily??) dependent on the outside daytime temperature.

If I remember correctly the operating temperature may be up to 700 F. (and no that is not a typo). I think I read this at a site that shuts down the unit when it hits about 350 F.
I set my thermostat at 80 f.
"The refrigerator uses three substances: ammonia, hydrogen gas, and water. The cycle is closed, with all hydrogen, water and ammonia collected and endlessly reused. The system is pressurized to the pressure where the boiling point of ammonia is higher than the temperature of the condenser coil (the coil which transfers heat to the air outside the refrigerator, by being hotter than the outside air.) This pressure is typically 14–16 standard atmospheres (1,400–1,600 kPa) at which pressure the dew point of ammonia will be about 35 °C (95 °F)."
