For comparison, I bought my new truck at the end of Jan to build a camping rig. 2014 F150 FX4, 4 door, 6.5 foot bed, 87,000 miles, and needed a little bit of work (shocks and springs) it's also originally a Canadian truck so there will be rust issues down the road.
$22,500, and that was the best deal for those specs in three states. I got it from 180 miles away.
If you want a 250 down here, under 50k miles, the price will start with a 3 0r 4. Under 20k will get you a 250 with 190-250k on the clock.
