Ok, I thought of an idea while contemplating changing my wife's car's wheels, how about some kind of air bag for a jack? I figured someone else would have thought of that so I looked online and found some. $800 is where they start!
So here is my question, couldn't someone (me for example) buy an airbag like the ones our coaches use, and rig a valve to it and use it for an air jack?
