If you lift the truck with the air bag, you have effectively increased the spring rate of the rear suspension. that will decrease the ride quality. the benefit of an air bag is to allow a lower spring rate when the truck is unloaded and increase as the load is increased. it allows for a better ride when loaded often, as it can keep the rear suspension at normal ride height under load and that makes the truck feel better. it can also offer stability when loaded as it has an increased spring rate. to get the benefit of better unloaded ride, you need to use the airspring as the primary spring, not as a helper. as a primary spring it can offer low rates that have a good ride unloaded and extreme capacity when loaded all from the same spring. going that route can be like kicking a can of worms over... trust me, hahaha
