On Wednesday the Waeco CRP-40 fridge arrived. Compressor, the smallest size model, with removable compressor which can be mounted up to 1.5 m away. I wired it up, and it is running fine, cooling down to 4 C. And with a small freezer compartment.
Somewhat no thrills, no light inside, no cover door for the freezer section. But very space efficient.
I also got a frame, which will make the fridge flush with the cabinet I am going to build around it. At the moment, it just stands in the rear of the vehicle, affixed with a few bunjee coords so that it does not turn over in tight fast curves.
