Pretend that I'm an idiot when it comes to the subject, and explain the advantage/disadvantage between the two, please.
I understand that with BOF, the body sits on a frame, basically, and the drivetrain is attached to the frame. With a unibody, the supporting structure is engineered-into the body itself. What I don't understand, is which one's better, and why. And why are pickups (aside from the Ridgeline) BOF, while modern cars (aside from the Ford Panther cars) are unibody.
