We head south each year about mid-January, but we have new rig with residential fridge. Because we take three days to reach the keys, we have a concern about keeping food. In the past we have done the overnight Walmart lot thing, but had lp fridge. Our idea is to pack freezer with all the food we can, and get some dry ice to keep things cold along the way. This way we wouldn't even run the fridge 'till we get there. Am I crazy or would this work? I can't imagine it would hurt anything, but as I said this is first for us. Thanks for your input.
