My '03 F350SRW 6.0 has been very reliable and cheap to run, EXCEPT when dealers got their moronic, untrained paws on it. 225K so far. (miles, not dollars

)
I have an early one, before they cheapened EGR coolers, oil coolers, and head studs.
My diesel guy only works on PowerStrokes, and he & his helper can pull the cab off a SuperDuty single cab in 20 minutes. (I've seen it done), slightly longer for crews.
But he has enough tricks that he seldom pulls the cabs anymore.
Not sure about the newer Fords, but at their prices, I'm not likely to find out.
Examples of dealership stupidity:
Back when my F350 6.0l was young, I took it to Sanderson Ford for it's 30,000 mile service. Left for Idaho the next morning, where I found that instead of draining the old oil (15 1/2 qts) out, they just added 15 1/2 qts of new oil in on top.

Blew every seal, gasket, & o-ring in the engine. They took several attempts & 6 weeks for them to seal it, and their half-a$$ed work lasted about a week beyond the warranty. Just recently paid big bucks to have it all re-sealed again. (by my diesel guy, never leaked since)
I hate dealerships.
Stopped at Keesee Motor Company, the Ford dealership in Cortez, CO for an oil change, told them the above oil change saga, & they assured me that they don't do those kinds of things. A few minutes later, they put the truck on a lift, and placed one of the lift pads under my 60 gal aftermarket fuel tank, putting a 3"x5" hole in it. (I had just filled it) They then refused to replace the tank with anything but a stock 29gal tank. After much discussing, yelling, threatening, & involving the police, they finally agreed to replace my tank- but in the time they wasted arguing about it, they missed the Friday shipping deadline & we had to wait until Monday. (We were due back in Phoenix Monday for work, and they had to pay for four days of hotel & a rental car) On Monday, they had to order a new tank, (almost $2K) then have it overnighted. (almost $2K) After installing it, they then refused to put more than 5 gals of diesel in it. More arguing, but we finally won.
On the trip we just returned from, needed an oil change, so I stopped at Bill Summers Ford in North Platte, NE. (been there once before) I also had an upper shock bushing on passenger side front shock go bad, so I asked them to replace it. Oil change was slow, but no problems. Then they came back with an work order for me to sign to replace all (4) shocks. ($2200!)
No, I explained, shocks are fine, just put in one bushing. They claimed it's all one piece, bushing pressed in, can't change it, BS, BS, BS..
After expounding on their monumental level of stupidity & dishonesty, I drove down the road to an O'Reilly's, bought a bushing & a socket, and changed it myself in about 3 minutes.
It is still there.
I could go on & on, but suffice to say I hate dealerships.
