CTD - Can you really expect 350K?

[EB]

A little over 2 1/2 years ago I sold my 95 Ram with 419,600+ miles on it. The man who bought it hauls vegetables out of the Rio Grande Valley of Texas to Houston, a trip of 350+ miles one way. It is still on the road. The last time I talked with him the truck had over 600,000 miles on it, still hasn't touched the engine. The only thing I ever did to it was adjust the valves and change the water pump a couple of times. Hope my 03 holds out as well, have over 255k on it now and still no problems with the engine, did lose the injection pump at 149k, but the engine is trouble free. (I consider the injection pump fuel delivery)
