I still have to figure a way to make it resistant to theft. I might consider wrapping a couple chains around it. But that is a bit tacky. Or possibly building a plywood cabinet around it with a hasp and padlock, which would be much more attractive.
If you're going to build a plywood enclosure, why not just build in a bunch of shelves and scrap the fridge? That would be equally secure and have more shelf space.
Insulation!
The garage is well insulated, with an insulated door. But it still suffers pretty severe temperature swings from night to day. Day time temp is aggravated by two working freezers and a refrigerator in the garage.
Storing powder and ammo inside a refrigerator will stabilize those temp swings.
