Good for you, OP! I am truly happy for you.
I loved my 2003 F-350 SC 4x4 DRW Lariat and would probably still have it if it didn't have the 6.0L. In less than 110k miles it had an injector, FICM, head gaskets, exhaust manifold gaskets, 2 turbo cleanings, 2 EGR valves, countless computer reflashes, ball joints, rear axle seals, and a bunch of other stuff I'm forgetting. The truck was extremely well maintained with all Motorcraft filters, had an EGR delete (after the 2nd EGR valve), coolant filter, and was babied, although worked with our 30' fifth wheel at the time. At the time I moved on from it, it had a bedplate oil leak that was making a constant mess in the garage, a bunch of weak injectors, and a failing oil cooler. It got to the point where we were nervous travelling far from home with it so it was time to go.
Not trying to rain on your parade but I don't think my experience was unique.....
