That is a really late build '07 btw. Another thing that folks used to worry about is low mileage 6.0s having stuck turbo vanes (folks called it lot rot). They made a machining change to the turbo, that yours would have, that virtually eliminates the problem due to rust, it can still get carbon build up.
I'm betting this is a good truck -- you also have the 3.73 Limited Slip axle in there (that would be pretty standard on an FX4).
I think you check it out and I bet you end up buying it!
Good luck!!!

Many 6.0s with over 250k miles with original head bolts and gaskets. I've got one.
For $3,500, he's talking about head studs and head gaskets with new oil cooler and EGR delete. That is a fair price. You can't add an BD Diesel oil cooler for that price though.
6.0 appreciate maintenance more than most diesels. Also, diesels want to be driven. Short rides should be done with gasers.
1) Is the coolant clean? Red flag if not.
2) check data. Check engine oil temp and engine coolant temp with some type of gage (not instrument gages).
3) Check Tranny fluid color. Needs to be a dark red.
4) Check voltages
5) Start it cold and see if there is a skip that clears up when warm. If so, there is an injector or two that need replacing.
6) Check the coolant level. It needs to be 1/3 full in the degas bottle. Get it warmed up (takes 20 minutes for this engine) and get on it really hard to see if it pukes from the degas bottle. IF so, it is either too full of coolant (that's why you look first), has a blown egr cooler or blown head gaskets. The compression leak down test is a good indicator of blown head gaskets. Although some say blown head gaskets sometimes won't show up in a cold engine.
Essentially, the best you can do is do a thorough test drive with some way to read data. Short of that, follow the above and omit the items that require gags.
I wouldn't be afraid of it. Most of hte 6.0 bad reputation is because of misdiagnosed egr cooler failure that takes a $500 repair and makes it a $3,500 repair to do a head stud job.
Good luck.
