Has noise in engine. 2011 Dodge Ram 1500 4x4 4.7. 220k. Clean beautiful truck. 20" tires in good shape, clean interior. But it has a engine noise that no one, including 3 shops and the Dodge Dealership can locate or know what it is. It has a knock. Ive been told it could be anything from a rod, wrist pin or even the fly wheel. I use it as a 2nd vehicle. Asking 3500.
