I got the tire changer all set up yesterday. It doesn't take up as much space as you'd think. The entire unit is probably around 600lbs. It comes in 3 main pieces. The base itself is probably 350~ish. I'm sure I could assemble a wooden base with caster wheels and be able to move the machine around quite easily if I wanted to. If you get a unit without the extra left-hand arm the weight would probably be 400 or so, and it's roughly 3' x 3' square.
