The 6.0 was brought out to replace the 7.3 in 2003 (mid year)
To borrow from Wiki:
Some of the 6.0 L Power Stroke
engines have proven to be problematic,
and speculated to have cost Ford millions of dollars in warranty repairs and buy backs. They led to many recalls and the repurchase of at least 500 trucks, particularly in the first year. However, aftermarket parts (e. G. Redesigned EGR coolers) exist to address these issues and, with them installed, the 6.0L engine's reliability improves greatly. The early engines had many problems.
Google it, the 6.0 is not held in very high regard by many.
If you must, try to get a 2005 year model or later.
