I really like my Lippert jacks. They are a really ingenious design.
I know quite a bit about how they work, due to a unfortunate oops. I gor interrupted when breaking camp before dawn, and forgot to raise the jacks.

I was horrified at the twisted metal that resulted.
After pricing new ones, I decided to try and fix them. It went really well, and nobody can tell it ever happened. In the process I learned just how they work. It keeps equal pressure on each pair of jacks making it impossible to rack the frame.
Hard to describe how it does it, but it is clever.

You should describe in a separate thread how you went about fixing/improving(?) them. Maybe I (and many others) could do something similar.

My problems have to do with: 1) the motors being exposed to the weather (lots of reported problems there), 2) the motors not stalling before the metal arms bend, and 3) the supportable weight varies with the angle of the arm.

Leveling pistons, like electric tongue jacks, pretty much solve all these problems, assuming the motor stalls before stripping the gears.
