Charley brings a good point up. They typically lead with a 110v power unit with the economy 4 post. I have "upgraded" some people to a 2hp 220v power unit that had a larger pump on it (like what is typically used on a 2 post lift). Probably worth requesting a credit for the standard power unit and applying it towards a better pump if you only plan to use it where 22o is available.

Now on the plus to the slower 110v power unit...it sure can be nice to push a lift outside and work in the daylight for washing, detailing or anything else. But I guess you could make up a 220v extension cord too.
