lippert 6 point hydraulic system.

We have a 2019 3120 legacy and are having a problem with the front right jack creeping down about 6'' when hooked to the truck. If I tie it up the other side creeps down,they don't hit the ground. Has this happened to anyone else.

Ouch!! Same issue on these threads traced to leaking valve or cylinder seal:

I had that on the right rear. It turned out to be a leaking hydac valve at the manifold in the battery compartment. Are you seeing any hydraulic fluid in there. Mine was hard to tell since it is so dark in there even during the day. I could run my finger on the bottom of the valve and get a drop of oil every now and then.

I have three jacks that don't pass the bypass test. Going into the shop on july 21. Hope they don't find more things wrong with the system.

Hydraulic Creep

Hi, we have a 2021 Montana 3121rl and experienced the exact same thing after only a couple of months of ownership. Turns out that if the system begins to lose pressure the jack that is connected closest to the pump and reservoir will start to lower. The problem for us was a leaky solenoid vale on the main distribution manifold, ours is also in the battery compartment. Was under warranty so I have no idea as to the cost. It took Camping World about one hour to put a new valve in.

Hope this helps. good lick,

Terry W

Mike... check batteries. I had same problem. Fixed it when I found batteries were not charged completely.

The rig has been in the shop for two weeks and they can't seem to find out what is making it do this. Went back to pick it up twice just to have it do when we hooked up to the truck. Hope they can get it fixed soon.
