I have an aluminum extension ladder that I use every other year or so

just leave it under the deck in the backyard? It will get wet but
shouldn't rust although I guess the rope that operates the extension
will rot and need to be replaced. Will the mechanism itself develop
problems?

Aluminum would be OK but any plastics, like the rope, would degrade more
rapidly exposed to sunlight.
Not much sunlight under MY deck - don't know about yours.
