I had real problems with this thing. It does not really fit under any of my cars, especially if it had a flat. Even if you did get it to fit, you could not see well enough to clear things like brake and fuel lines, or exhaust bolts. I barely got it to fit under my 1/2 ton truck. And I stopped adding air before it lifted off the ground. The 'frame' on my truck is just not really wide enough, and there are to many things around that the bag was starting to hit. I thought it might explode if I added any more air.It did work well on my old tractor. And I suspect in an emergency, in a place where a regular jack would not work, I could get it to work on my truck.
