Well I traded this weekend and now own my first Diesel.
Its an 05 F250 King Ranch with the 6.0 PS. I traded an 02 F250 Gas that I'd been using to pull a steel 3H gooseneck. It did OK but I am looking forward to being able to climb hills now
The truck has a new motor. Apparently this one had motor problems and Ford put a remanuf. motor in. The dealer bought it at auction. I spoke to the service manager at the dealer about this and of course was reassured that they had a handle on the 6.0 problems. Wish me luck.

Nice truck! Congrats! Don't worry, it should have the balance of the warranty intact. Most 6.0's are just fine but we do run into one from time to time that gives us fits. Enjoy the new power!!
