The 5.4 is well known for the spark plugs breaking off in the head when you change them at 100k, which in a lot of cases requires pulling the head. There are also issues with the cam phasers on the 4.6 and 5.4 that control the cam variable timing making noise and eventually failing, which leads to a loss of power and rough running. That's not a huge or expensive fix though, and should be obvious with any good inspection.
Overall they are solid trucks, I just can't stand the lack of power. It makes passing on a two lane "interesting".

The cam phaser problem is one that can be diagnosed by just listening to the motor run, Most times it a series of ticking sounds that get louder the worse they are. I have heard an F150 or two going down the road that must have been really close to breaking some internal parts (really loud ticking) but still going down the road with an obviously oblivious happy driver.
My 2004 Mustang GT DD 4.6L currently has 165,000 miles with no ticking, and has given me no problems.....I will buy another one.
I have driven Ford pickups for 35 years now, and other than brake issues, they just seem to keep running faithfully for me.
