Stock? Pfft!
No, with the airbags properly adjusted, the truck should sit at it's normal empty ride height. All of the components that normally handle the load (springs, axle, wheels, tires, brakes, etc...) are still required to do their job within their rated design. That being said, yes I have overloaded my truck with them. Whenever I go to get topsoil or mulch I fill the bags to 95 psi. The guy loading me usually just watches the suspension and when it squats he considers it a yard and a half.
