airbaging a system is pretty simple, but im saying that its not the best proven setup for wheeling... lots of fabrication will be needed and in most cases will not be anywhere near as cheap....
you can only get so much lift with airbags, and with air in them, that can limit travel and compression, i also dont trust the fact my truck would be riding on giant ballons...
many people will then compare the idea that the big rigs use air bags, and they do, but their system is a lot different that the huge offroad lifted airbags you see on the street queen trucks...
