Another data point, as long as we're throwing them out - I park my COZY
MKIV outside at KFIT in MA.

One more. My Maule has been parked outside since I bought it in 1995. Since the
venting system has no anti-syphon devices, it has a tendency to dump fuel if I
park it with the tanks near full, so I have not done so since shortly after I
bought it. I check the tanks during preflight, and, if they're down around 3/8,
I fill it back up before flying. I'm based now at Lakewood, which is a few miles
from an inlet of the Atlantic. I've never seen any water in the fuel.
