I did some tests with my 85 fridge unit I now use in my 87 syncro westy
conversion.
After several days and weeks of testing. My particular fridge could only
hold about a 40-45 degree differential between inside and outside air temps.
The fins would freeze up and make ice in the evening but on 95 degree days
the ice thaws and the interior temps reach well above the required 40 degree
max for a fridge to be safe.
I hope that the 182 b performance varies and I can find a cooling unit that
performs as you state.
My overall feeling was that a 40-45 degree differential is not sufficient
for my needs and I have looked to Engel and other possibilities to create a
better fridge situation.
Perhaps if there was a modern day version of the 182b that could be
purchased new that would help, I also feel a "hybrid" between a propane
powered fridge and a highly efficient swing compressor system used in tandem
would be ideal so you could run the fridge efficiently on DC and offer temps
as low as 0 degrees F on 100 degree days.
just my .03
