hwh jack cylinder shafts do not rust. american made stainless steel does not rust.
the outer tube and the housing are steel, and will rust. even on hwh.
chrome plated steel like some other manufacturers use will rust.
the newer hwh jacks with nickel impregnated steel shafts do not rust.
impregnated means molecules of nickel combine with the steel molecules in a way that they are intertwines with each other. not just adhering to the surface. the standard test for corrosion is 100 hours of hot salt water spray. the newer shaft showed no corrosion.
as far as storing jacks down or up, its your money. your operators manual should tell you what they think. or call the manufacturer.
in the end, its your coach so its your choice.
