Went to the dealer today to make an appt. for a tire rotation (don't ask), before I left, went to look at a '07 chassis 3500 DRW. The door sticker had a build date of 11/06, and the plate on the motor had an engine build date of 10/16/06. Also, btw, said 305 HP @ 2900 RPM. This was a white auto with a sticker $$$ of just over 32,000. The options sticker listed the Cummins at still $5,555.
