I put BAL scissor jacks on our Axis. They don't level, they can only stabilize. Thus I use blocks/wood/etc. to get the coach level and then drop the scissor jacks.
Sure the jacks are rated for more than the weight of our coach but I would never be able to lift a corner with the jack (manually or using a drill).
You can get scissor and other types of jacks with electric motors built on them but even then I don't really think they can level--only stabilize.
