Thanks for all of the welcomes and all of the info everyone gave...very helpful. Any idea what "option #4C42AA deluxe air heater" means? I have talked to so many people and this one question has everyone stumped. Does it mean that it has factory ac? The truck does have factory air now, I'm just trying to find out if it came from the factory that way, if it was dealer installed or if it's been installed after leaving the dealership.
