in my dream world, i'd find a black 7.3l f350 four door long bed 4x4, with a manual trans in pretty good condition for under $10,000, knowing that it might have some miles on it.
Do a lot of homework on 7.3s and (if you must) 6.0s before buying such a thing. Scotty's Excursion is a sweet truck, and you can see how much work has been done to it. These are expensive trucks to maintain (2 batteries, 15 qt. oil changes, air filters, various Ford bugs (alternators, starters, ball joints, transmissions) and licensing. If you purchase 'any old Ford Super Duty' from a private party or dealer, you could be buying a ticking time bomb. Spend time on the FTE forum and read up before you buy. It's far easier buying a used Toyota, but I love my Super Duty for the big jobs.
