It was an 07 with a 6.0. It only had about 106k on it, but it was a 6.0. I thought - how bad could a 6.0 really be? It can really be that bad. And I did't have any of the really major stuff. Just a couple injectors, an EGR valve, a high pressure fuel rail o-ring, a catalytic converter plugged up, and a EBP sensor go out. All within about a year's time from when I bought it until I sold it. Ugh. It basically broke down every time I drove it. But - silver lining - I actually made money on it despite about $5-6k in repairs in one year on it because the truck market is so good. I can't believe people will pay $20k+ for low mile 6.0, but that's the world we live in now. I was happy to see it go.
When it wasn't belching black smoke or dying on me - it was really nice to drive. Powerful, smooth, reasonably quiet. Mine was totally bone stock down to the wheels and tires. No tunes or any mods. It was just a beater truck to have around for towing and hauling stuff. And when it was running it towed and hauled like a champ. Just not reliable enough to keep as a daily driver.
I think the 6.7 was finally a decent motor for Ford. My brother had one for a few years and had nothing but positive experiences with it.
