Hydraulic Landing gear, slowly moving while enroute

Just over a year ago when we picked our 5th wheel up to bring it home, one of the landing gear had to be replaced because it wouldn't stay up. The other one had already been replaced.
Our last couple of trips we've noticed when we stop for the first time one of the landing gear has dropped 2-4 inches. We push the button, it goes back up and stays for the rest of the trip.
We have plenty of hydraulic fluid, not sure what else we should be checking to see what could be causing the problem.
Any suggestions?

A fluid leak in the system. Check all the hose connections to see if you have leaking fluid visible.

ditto:....fluid leak or faulty check valve

If fluid is at the same level (no leak) then a check valve possibly, or the main valves are not being fully closed electrically.

No visible leaks of hydraulic fluid. We're not sure how to see if a check valve is an issue, is there something we can test?
Lindy - you mention the mail valves are not being fully closed electrically, any suggestions on how we test for this?

When I had hydraulics (glad I have electric now) we went through lippert solenoid valves fairly often. Never had the jacks drop but the slides would come out while traveling.

Could be internal seal leakage in the cylinder causing a bypass of fluid, allowing the jack to drop.

As IGOTJAM mentioned he had issues with the solenoid valves, there are specific OHM reading for each valve you'll have to check with the MFG for what these should be.

Coil is required to open valve. No power, bad coil = valve stays closed and won't open. "Leaking Down" will have nothing to do with "Ohms Readings".
