I'm guessing that the people that full time don't retract their levelers very often.
I always store our coach with the levelers down. The cylinder that you see is not what rubs on the seal so a little dirt doesn't hurt anything.
I think you need to tear one apart and see how they work.
Or just read the manufacturers information where they say that the galvanized cylinder that I see with my RVA hydraulic leveler system does NOT rub against the hydraulic fluid seal. The manual says:
The dull finish and scratches have no effect on the sealing capability of the jack. The ram that extends out of the jack is 1/4 inch smaller in diameter than the sealing area in the jack, and the seal is only on the top section of the ram. The ram is cadmium plated to better resist corrosion, however it can become scratched but it will not affect operation.
