When I arrived at my camp site this afternoon I noticed my passenger side front leveler was down about 3 inches. Does anyone have ideas why this would be happening?

It may be a calibration issue. Run the jacks fully up and down several times. If the drift continues, try looking at a leak somewhere.

it is probably the valve on top of the leveler. They have been known to go bad.

I ran them up and down a few times and wallah it seemed to fixed the problem. Maybe it was air in the line or something. Thanks for the help.
