Sorry to say this, but it sounds like the damage may be a little more extensive than bent rotors. Everything on brake systems must line up true no matter what the vehicle or you'll have problems. Stop and think of the force you put on the wheels, rotors and everything that they are attached to by hitting them with that much weight. No one in their right mind would take a sledge hammer and pound on the rotors while they're on the truck. What you did was a lot worse since the truck weighs a lot more.
