From what I understand, it depends on the length of your rig. We had the 3.0 ground control (electric) installed on our rig at the rally in Goshen this year, and love it. While another club member had the 6 point installed on his coach. We both have the Elk Ridge, but ours is 30' while his is closer to 38' (don't know the exact length). If I remember correctly, they told him he'd be better off with the hydraulic 6 point leveling over the 4 point electric. He already had hydraulics on his unit for the slides, while ours only has electric. I didn't want to have hydraulic installed on ours, as that would have added more weight, and would have taken up more storage space, plus the added cost.
Ours works the same as the Level Up, but it's electric.
