My theory is a little different. The insulation is snug to the sides prohibiting much air exchange. I see the wall insulation functioning as adding 3/4" insulation to the fridge side walls making them more efficient holding cold in the fridge. The fridge is in now and working nicely. The next thing to see how well it works is the Insulation on the outside wall and how well it keeps sun shine generated heat from entering the fridge compartment. Today was that test and the fridge maintained a steady temp with no elevation throughout the day. Well see what happens with more time and observation.
Maybe in your camper the wall insulation and fridge insulation snug together, but on mine it does allow for some air circulation.
Still it it the part with coils that is crucial.
With no insulation AC helps in cooling the compartment, so refrigerator is more efficient, while insulation makes it working with hotter air.
I parted 1 of my campers and refrigerator is now in Sprinter conversion working on electric only. No vents, so it is using interior air, just like household units do.
Th fridge is over 20 years old and it really works nicely, even 100F for me is spring temperature.
I think lot of owners have issue with them due to poor adjustment, or overloading the fridge, so there is on air circulation between fins and the food.
