I just swapped out my MRE supply. It's a 7 day supply, not too bulky. I rotate them on 36 month basis and I've decided I want to up the cycle time to at least 48 months, if not 60 months. Cooler storage = more shelf life. I know that.

Here's the problem. I really don't have a "cool dry place" to store them. My woodstove is in the basement, which is wonderful, but the basement is 75+ degrees all winter long. My attic is cool and dry in the winter, but an inferno in the summer (130+ degrees). My garage is too hot and too cold no matter what time of year. I don't really want to spend the time hauling from place to place, I have a small house and allocating space is a big issue.

We are seriously thinking of digging a "root closet" directly out from my basement under the garage slab (garage is attached) - but I'm wondering if I'm missing some obvious ideas here. Can't involve electricity.
