If you like the one with 114000 miles have it check out by a different shop that knows powerstrokes they can tell you if it's good or bad. If the truck is clean and I mean the seat doesn't have alot of wear body not all dinged or blasted and scratched form to much off roading.Check the bed, not all dented up if it has a removeable bed liner look form underside of the bed for damage. Look for signs of a wreck, or repaint. You don,t want to buy someones elses problems.
