Now the control system may look different but on a DRV with rams front and rear it probably functions pretty much the same.
There are some MHs that use an external spring to return the rams to their stored position but those are usually older models; Newer spring return to stowed rams have internal springs.

So newer MH's use the same/similar Lippert leveling system. I said I hadn't seen them. And I'll admit I don't on a regular basis crawl around and look under MH's.
Although the last MH I had the pleasure to look under (while hooking up straps to help pull them out of the mud at a CG) did have the 'spring' version.
DRV's as well as most of the towables adding LevelUp use 6 point leveling, with the rear jacks on the same side floating as the front is raised or lower.
The Lippert jacks are dual action, hydraulicly moved up or down and no internal springs.
