i appreciate the offer dmov, but i buy new now. I have run some of the most dated trucks in the world growing up, and when i finally bought a new Peterbilt in 99 i learned the value of warranty, service, and exactly what “pride in ownership” really meant. i usually buy a truck and keep it,,,forever,,,,. I service engines @ 10,000mi. grease every 5,000mi, and use only quality oils and lubricants. I found the Petes are for a lifetime if well cared for, as i still have a 79 model 359 that is still capable of otr service ! D.
