Not all hydraulic fluids are hydroscopic. True petroleum based oils are not. Even transmission fluid is not hydroscopic. The water comes from head space in the reservoir and temperature changes which causes condensation to form on cooler surfaces. If you get a cap for your reservoir that prevents moisture from entering, you won't have a water problem.

Lippert recommends the fluid be changed ever 36 months. I was having some problems with the slides creeping out with weather change. I changed the fluid and problem was solved. The hard part was getting the fluid out of the reservoir, ended up using a turkey baster.

If people would put left square bracket url right square bracket before a link and left square bracket /url right square bracket behind it, their links would be clickable!!!! Chris

When should the fluid be changed and what is recommended?

Without leaks the fluid should last many years. It a closed system that is lightly used. ATF fluid is a good hydraulic fluid.

The red color is good for identifing that it is leaking.
