Sounds like you have a plan, and it is working great for you. Nice job!!I've found that my daily chore of swapping out my 2 ice blocks, between Iceco freezer and my sportsman's cooler have, in effect given me the full benefits of having a refridgerator and a freezer working well for food storage in my Suburban. I've never bought ice, while doing this and it's been effective, even while staying in the desert in Arizona during hot temperatures.
