Sounds like my friend. He does just about all of that. Sadly his '04 2500HD would not take it.
Things replaced within 25k miles
-rearend TWICE
-exhaust manifolds once
-headgaskets once
-ujoints twice
-ball joints, tierods, and few other things once
Like I said above, anything over 30* temps the plow had to come off because the truck would overheat. He had it to the dealer multiple times and there was nothing they could do other than tell him to take the plow off when not using it. That’s all fine and well if you only plow your own driveway, but it was a work truck.
He has an '02 F250 now and a '99 F350 with over 100k on both and they have yet to let him down. He got also had an dually diesel GMC, I think it was an '08 and he got rid of that too.
