Thanks Mike. Ken suggested that I consider using a factory made frigeration/freezer unit and replacing the electric motor with a Watermotor, rather than trying to adapt an auto a/c system. If that was practical, it would probably be the way to go. The Watermotor 90 is quite small. Perhaps even replacing a worn out factory compressor with a auto a/c compressor, as well. Those cost about $5 here. Ken also wrote about using propane as a refrigerant gas. Interesting idea. It seems to work. Ron Davis, watermotor.net
