Oh ok. I call um a 4 post lift.....but I can sure see why some might call them a stacker. lol
Looks like a stacker can lift more than one.
If you need the room, and have the height, and budget, the stacker is a no brainer.
i have a 4 post and really unless you're working under the car every other type of operation is cumbersome. if you're trying to do actual work, a two post is where it's at.
that stacker is slicker than deer guts on a door knob.
