Exactly!! If is sounds like one DONT get it. If you do, then prepare on ripping valve covers off and replacing lash adjusters, cam phasers, tensioners, etc....
My last 04 DID sound like a diesel, my current one does not. just youtube 5.4 cam phaser to know what to look for. Dont mistake it for loud fuel injectors (these trucks have loud fuel injectors)
Other than that, alot of people get alot of miles out of them. When i was looking here were my things to look for as I read they are notorious problems on these trucks
1)Cam phaser diesel noise
1200 dollars in my case. 74000 miles.
2)Exhaust manifold leaks (which I now have), mostly on passenger side. you can tell if you hear a ticking noise on acceleration
Dealer fixed for me. Mine is an 04. I bought it last July for 17000$ 73000 miles.
3)Bed shake, make sure it doesnt shake too bad going down the highwy at cruising speeds (my last one did, drove me crazy)
At 60 mph a vibration that causes bed shake. Have not addressed. Just stay above or below the shake zone.
4) Make sure all power windows work, regulators suck in these trucks (just replaced one) No trouble there yet
5)Tranny shudder - almost every F150 i drove had a slight shudder when releasing pedal and reapplying it
I am blaming my warped rotors. Not sure what this would feel like.
6) If buying from a dealer, MAKE them change spark plugs before buying. If not it sucks and cost alot to have to change. just google 04 f150 spark plug issue (the plugs are notorious for seizing in the heads)
500 dollars out of my pocket.
Other than those few items, these trucks are great and not all of them get these issues, but after reading up on the forums, these are the most common issues to look for

2006 SuperCrew FX4 with 3.73 gears, 2 adults, 1 kid, toolbox with various recovery/fix-it stuff.
before blower
12.5 city....it went up/down....but pretty consistent
18-20 highway....I drive nice and use cruise control
after blower
12.5 city with tons of full throttle action
no idea about highway
if you are a run and gunner on the highway, you can expect 14-16 mpg easy. carry a bunch of crap in the truck...same story. oversize the tires from the factory 32" height...again, huge MPG hit.
you'll be annoyed at how much lower the MPG's are for the gas vs. what you currently get with a diesel
the 5.4 3v is a powerful motor, but it isn't helped by the 6,000 lbs weight of a SuperCrew 4x4 F-150
I'll never go back to a F-150. I loved mine with the supercharger and the leveling kit....but I've seen the light

Oh and tylus you may be regretting that statement about seeing the light when that 6.blow your driving starts to dollar you to death...lol...sorry I just had to say it being a 7.3 guy myself.

She has <13,000 miles at moment. I'm pretty risky
I honestly wouldn't be adverse to popping a HG right now so I could justify studding to the wife and then upping the boost and a SRL+ tune
