I have a BendPak 4-poster, and I love it!
My shop ceiling is 12'-6" height, and I can put a full size van on top with room for the Z underneath if I choose.
I got the lift with the optional casters, so I can move the lift where I please. I have even moved it outside in the driveway to power wash the underside of my cars.
The lift takes 220 volts for the hydraulics and a source of compressed air for the safety mechanisms. I just use a long 220v extension cord and an air hose to allow for moving the lift around.
Get a couple of the fixed sliding jack trays and some short bottle jacks, and you are good to go.
