99 F-350 diesel with 190000k on it and it still runs and looks great. I have had the high pressure oil pump o-rings replaced twice but I do tow a large living quarters horse trailer with this truck. Replaced the water pump at 95k, other than that this truck has been awesome. No doubt this truck will go 200k plus with no major repairs. our 2002 450 has had rear end issues since 18k, 5 times in the shop still not fixed. At 90k at feel that it is ready to implode! Other than that it has been solid. I'll still buy Ford.
