Ours is the 6 point electrical lippert level system and it came with the strongarm from the factory but only time I use them is if it's going to storm.
I've heard the same about them not working with the hydraulic level. I also use blocks to minimize the leveler stroke and ours is always very stable. After a day of sitting I hit the relevel button to let it relevel from any ground settling.
