Freezer in unattached garage in northern Ohio during the winter

2. Rust and mildew, maybe

We keep our freezer in our outside car port, it tends to collect moisture on teh top and get mildew.
But we also keep it plugged in.
The one blessing from having 2 freezers outside in 2 different houses, over the years, was that when we lost power,
the freezer held kept everything frozen for days,, and in the winter power loss, I could open the lid and the freezing nights would do the trick.
