I’m not familiar with a hydraulic systems as ours is electric. I do know that ours requires a minimum of 12v to function correctly. Random errors can occur with inadequate voltage. You could connect to an inverter generator to get the voltage up and try the leveling again.

Make sure that your 50 amp service is wired correctly for RV’s. You’re a pro so you’ve likely looked into the correct wiring but just a word to the wise. Too many have made the mistake of thinking it’s the same as a dryer plug.

Welcome to the forum. Let us know how it’s going.
