Keeping Jacks Down for Storage to reduce tire flat spots

You're right Tom. I was a hydraulics engineer at Boeing for 20-odd years and I know the pistons don't exit the cylinder, plus, they're usually made of aluminum alloy with O-rings.

I was surprised that the rods on my Georgetown were as sensitive to atmospheric corrosion as they were, but maybe I wasn't clued in to the salty atmosphere when you live across the street from salt-water waterfront.
