Thanks guys, ultimately the stacker/lift/hoist would be for working on vehicles as opposed to storage, the majority of time. That being said the cuda gets stored from Oct/Nov-April and I'm sure that I would need the "hoist" to work on other vehicles.
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.
