You don't say if it is a crew cab, extended cab, or regular cab. Nor SRW or DRW or trim level (XL, XLT, Lariat). All those are considerations about price. A regular cab, SRW, XL with few or no power options should be priced at least $5,000 less than a DRW Crew Cab Lariat.

As the other guys said, mileage means less than how it was cared for. I bought a 2001 that had been on a Ford lease all it's life. It had 266,000 miles on it when I bought it and drives like a new truck. I had to do front brakes because of sticking caliper pins, but the rest of the chassis is pretty much like new. It was cheap because it was a XL regular cab.

Anything with over 100,000 miles will need some TLC for something. The depreciated price helps compensate for things you'll have to pay to fix. Plan for it, and it won't be bad.
