Before we got our Engel refrigerator, I had been working on designing an icebox that would allow me to keep food cold and dry. Nobody likes soggy ham and cheese sandwiches. When I was digging through some old files I found these designs I made for a working Icebox that allowed for easy ice changing and kept the food dry. I never built it because we went solar powered compressor driven, a much better choice. Thought I would share this anyways.
