What should I use for Hydraulic Fluid in this system?
If you have a Lippert leveling system Type A Automatic Transmission Fluid will work. ATF with Dexron III or Mercon 5 or a blend of both is recommended.
Make sure the leveling jacks are in the raised position when you check the fluid level. Adding fluid while the jacks are lowered can cause a mess when the jacks are retracted and fluid in the system returns to the reservoir.
