Since it has gotten away from Ferde trucks, my 02 Duramax has 304,000. It has original engine, trans, and both diffs. Also has the original front brake pads. I mainly use it to haul my shooting equip. around the USA to shooting matches. My old Mitsubishi that I drive daily back and forth to work has 284,000. It is still an excellent vehicle, but a customer just gave me a clean 2009 Toyota Corolla with 175,000 on it to replace the Lancer.
The Corolla has a blown head gasket that is getting repaired.
