My 2003 had computer problems, it had to be reprogrammed almost every two months by the dealer, but I did have one of the first ones out. When I sold it, I knew that the head gaskets were shot and I had two faulty injectors, but it was still under warranty so the new buyer had it done.
My 2006 is an absolute dream, wouldn't want anything else.
I did have a F350 so it is a little lighter than the F450 and it is geared differently. I had high speed rear end (3.73) and I was averageing 14mpg city and 19mpg highway. I was chipped and was putting down over 400 HP on the pavement so the linkage at the kneecap would freeze up sometimes and kept the accelerator pedal to the floor, so it could be a little lower than that at times

Same here have an '04 F550 with 5 injectors 2 turbos and the heads replaced in less than 28k. Great trucks for hauling and I love the way they drive. With that many miles the problems would have appeared by now though so you should be ok.
