It is above it, but there is a chimney through the evaporator/boiler that takes the heat around and above the rest of the coils.

I don't really understand all of the plumbing on the back of these things, I have had a couple go bad in my buses over the years, pull them out and there are lots of steel tubes running around on the back of the cabinet.

Fortunately they went to household side-by-side referigerators in buses back in the '90s, but most RVs still use the ammonia systems so that they can cool without electricity using the propane flame.

I understand that there was a lot of ammonia used in commercial refrigeration also until fairly recently.
