Here is one other high mileage data point..
Bought truck new. One owner.
250+K miles on 06 Dodge 4X4 3500 CTD dually, most with camper on its back. Truck is stock.
Replaced clutch, ball joints, tie rods, U joints and water pump at about 240K miles, replaced AC compressor at about 220K, had one injector replaced at about 150K, Dodge covered 80% of cost of defective manual tranny at about 50K miles (only 36K warranty). Have one auto door lock not working right now. Other than brakes and caliper replacement and other regular maintenance that is about it. Very happy with it and plan to try to get another 250K miles.
