The 6.0 isn't that bad we have one that's stock and doing fine and my buddy has one chipped on stock head bolts and everything and its still fine
From the nuts at work, the 6.0 is great stock. You start modifying and then things start to break.
Most guys are nuts about the dodges. Only one 7.3 Power stroke guy here.
We had a 7.3L powerstroke dually at my last job. The day I started they sent me to the dealership to pick it up. Had 3 miles on it. I put 120k on it, no major problems. RELIGIOUS oil changes.
in 120k we replaced a water pump, tires and brakes. Last I heard of the truck it was over 300k and had went through 2 sets of injectors, a couple water pumps and some other minor things. Sensors and the like.
We had a F250 gasser at a strip mine I worked at in 2003. It had 400k miles on it. Truck was a TANK! The day shift had it to run parts in, on the road all day, afternoon and midnight had it to go inspect pits. It was never parked for more than a couple hours a day.
Major repairs: 2 Transmissions, 1 rear end.
Minor repairs: General maintenance stuff plus sensors and other little things.
Let me say this. This truck was BEAT. No one took care of it. We would run down the dirt haul roads as fast as we could and laugh are butts off as we bounced off the ceiling. I rolled it on its side in a ditch one time. We tore it up. Nothing inside of the truck worked, none of the gauges, power windows, radio, ect. The only thing that worked was 1 speed on the blower and the heat. It would be HORRIBLY overloaded(hence the transmission and rear ends)
That truck there sold me on Fords, although I drive a Dodge!
