We have the hydraulic Level-Up from the factory with the Alta remote. No document revered to a system version number. While the wiring is messy, it does work. Over time I will be cleaning things up and documenting them on my thread here
Once I hit the auto level button, I just go on with my setup and let the system figure it out. Our 3715BH has 12" frame rails so I think they were less concerned about distortion. The Lippert frame came with the jack mounts welded on. All the hydraulic jacks are at an angle to the frame. I can level it in the street in front of my house and the curb side wheels will be off the ground. Not desirable, but there it is. With 60,000 pounds of lift, the jacks can hold 2+ trailer weights.
