The 6.0 can be a good truck, but buy one on its records, not its model year. The well-known trouble spots are head gaskets (the factory torque-to-yield head bolts stretch), the oil cooler and EGR cooler, the FICM (injector control module), sticking injectors, and the ICP and IPR sensors.
The number one pattern is that the oil cooler plugs up, the EGR cooler then gets too little coolant and fails, and that heat and pressure can lead to the head gaskets. So the first things to ask about are oil cooler and EGR cooler history, and whether it has head studs.
On the early ones: "worked out" is not quite right for the Excursion. It only had the 6.0 for 2003.5 to 2005, and the bigger fixes came later in the F-Series. The 2003 actually has the round EGR cooler, which holds up better than the square one used from 2004. All 2003 to 2005 engines share an undersized turbo oil drain tube that was not upgraded until 2006.
Transmission: with the 6.0, Ford switched from the 4R100 used behind the 7.3 to the 5R110W TorqShift five-speed. I have not seen solid data showing which one lasts longer, so I would not buy on that. Have the fluid and service history checked like any used automatic.
Before buying, have a diesel shop scan it and compare engine oil and coolant temps on a drive. A big gap between them points to a plugged oil cooler.
