I have the exact same truck, color and all, also with a custom bed. The body lines won't change when you add air bags. The bags are a "suspension lift". Now a "body lift", that of course is a horse of a different color. I thought the same thing when I was looking into adding the bags, but the fella explained it to me and all is good. I think that without the bags, I would have done a good bit of damage by now. Rig weighs 11,800 lbs. with truck and machine full of fuel. The bags were a great investment.
