I can't believe the size of some of these things. Buddies have theirs in the garage, but here in the frozen north, condensation is always an issue. My solution was to not buy such a big safe to begin with and not buy so many new guns, an abhorrent suggestion to lots of the Fire folks. Honestly if it wasn't for the F-150 and gravity, backing the safe down the stairs into the basement wouldn't have happened.
