Baggin any vehicle to lift or lower will result in a pavement queen that is rather bouncy. It's ALL about looks with bags.
Most guys on here including myself use rear airbags as helpers, not for the purpose of raising the ride height.
I think the cheaper otion is to just stick with a suspension lift and call it a day. This way, you can have a suitable offroad truck if you wanted to or if you decided to sell it, your crowd that would buy it isn't so limited. I wouldn't buy a truck with airbags on it for a lift, but I would buy a truck with an actual suspension lift.

 

i hear ya dirty. it does sound easier. it is really not an offroad truck. I have a 2 door cherokee that i use for everything else. just thought the "cool" factor would be, well, cool. but then again, i dream a lot.
