I think there is misunderstanding about the concept.
Insulating the compartment for hot weather usage prevents the cold from the camper to escape via compartment open to exterior air.
This way the compartment stays hot -eventually making fridge working harder and warmer.
My Fleetwood had Styrofoam insulation on those walls from the factory.
Couple years ago I did tests on my fridge and it was giving -6 in freezer and +1F refrigerator on 103F afternoon, when empty camper interior was at 99F and fridge wall was facing south.
Not bad for 18 yo fridge.
I simply keep the fins clean and check top vent screen.
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.
