On my Lippert leveler system the fluid is visible in the tank in the basement.

I have a 2010 Caribbean and the Lippert unit just went out on it due to hydraulic fluid leaking into the motor .
Lippert has replaced the oil seal between the tank and the motor with a new (better) one , mine was the old style and the folks at Lippert were great and replaced the motor and oil seal even though the warranty was up by some 10 months
