Wht is the purpose of air bags? It appears that they are mostly added when someone is nose heavy or overweight for the their truck. True or not? Benefits or reasons to avoid? Thanks!
I had them on my old F-250 and will soon have them on my new F-450. They didn't increase the capacity of the old truck and I don't need more on the new one but I like being able to level things out once I'm loaded.
