Yesterday it struck me that the dometic in my family's camper is older than
the one in my Westy, yet it cools more like a regular refrigerator. It
makes ice and has a small freezer compartment, like my grandmother's old
Servell ammonia cycle refrigerator. I am trying to figure out what is it
about the larger refrigerators that work better, if that's indeed what it
is.

Is it the size? Is it the fact that the camper fridge is almost always
working in a temperature-controlled environment, and is never allowed to
get really hot? If so, why did the Servell in my grandmother's house work
so well, when it wasn't air conditioned? Is it the amount or quality of
insulation?

Just wondering, if you know.
