This was a pre-owned company truck with 48,000 miles. As expected it showed some normal signs of wear but also signs of good maintenance. Put fresh tires and shocks, wash and polished - good to go! I use it to pull my small travel trailer and have put about 15,000 miles on it with out a problem. Gas mileage when towing is 13-15 (@65-75mph more often 13), solo 18-20 (not often 20 though). Happy with this truck.
I've had a lot of problems and looking online, so have others. problems with the brakes, upper control arms (having to be replaced again), front hubs had to be replaced, leaking power steering hose, and now exhaust manifold has to be removed/repaired. I only drive 5k miles a year, except for one year when I drove it for about 20k. For a 4x4 truck "Ford" tough, this thing is anything but tough. And I rarely go off road. This truck has been babied for the most part with no rough treatment. Seriously considering getting rid of it for another brand. I used to be a Ford man, but after this truck, I'd have to think long and hard before I buy another Ford product. Very disappointed.
I took a chance on this truck knowing Ford has had reliability issues in the past. My brief experience with this truck, before I returned for a refund only, reinforced this concern. The truck, an EcoBoost 3.5L V6 version, was experiencing significant Engine Timing Cover Oil Leak at only around 40k miles. Online searches turned up many others complaining of the same problem. Also, take this for what it's worth but online searches of the EcoBoost 3.5L V6 F150 turned up a lot of complaints of sudden loss of power on highway under acceleration as well which I found to be pretty alarming. I will admit I was impressed with the acceleration but I never did get close to the advertised MPG stated by Ford even when I was driving conservatively.
