I'd imagine the damp isn't much more than the humid down here in FL... I have tons of electronics outside, haven't had any failures on any of them or my welder (not Everlast, just got that one a few months ago.
I wonder if making sure it's completely cooled down in the winter to avoid temp differentials over longer periods would help avoid condensation issues?
You could always bag it with dehumidifier packs for longer storage, no?
