How many miles? Any existing warranty would be a big plus.. Any prior service records/docs included with the truck?
First thing you might want to do is have your local Ford store run an 'Oasis Report' off of the trucks VIN number.. It'll give a history of work done 'both' in repairs, and warranty done at the 'dealer level'.. If you don't have one local, email me your VIN and I'll have the report run..
The 6.0 has a bit of a reputation as a problematic power plant, and their a high tech/complex diesel and something to consider in a purchase.. Mine has been trouble free @ 75K now and gets used reasonably hard towing, but many haven't been so lucky.. The S/D is an awesome build truck IMO, and the 6.0 is great for heavy towing/hauling, but can be more expensive overall in repairs and maintenance over a gas powered unit.. Some may say 'no way' to a 6.0, but I've seen many run'n hard with no problems, but also have been witness to those that have not.. Not that other manufactures haven't had issues either..
The 6.0 has had a lot of issues bleeding oil.. Most are just annoyances as a hanging drip.. A quick look under the truck at the lower bell housing area and along the oil pan/bed plate may reveal any possible leak points, and tend to collect on the lower bell housing.. Head gasket can be an issue (more so depending on how the truck was used, or if a programmer/tuner was used to add more HP to the engine..
I'd try and get some history on the truck, look for any leaks top to bottom, and look the truck over as close as possible to get an idea of how it spent it's 'previous' service life.. Any larger exhaust added, gauges, lifted, and fifth wheel hitch (on or removed) ect. and match what you find to the oasis and service docs to get you best bet on a 6.0.
Would I buy another? Sure,, I love mine, and it's like a 8K lexus even pulling my tractor.. But also with the possibilty of future repairs/higher maintenance costs (especially if out of warranty) and depending on what I saw and found on both the truck and with a reporting or supporting docs as an informed decision tool for a purchase..
