I had a major problem with the transmission and it needed to be replaced. I had bought the extended warranty and Ford bought the tranny, a u-bolt and rear section of the drive shaft. No hassle, no problems. This is one of the best looking and best performing trucks I have ever had. I will probably keep it till the wheels fall off and can't be put back together.
Comfort is great. I have driven this truck for 14 hrs. stopping only for gas, and it was just as comfortable as my Toyota Avalon if not more so.
Gas milelage is not what I had hoped it would be. 3.6/V6, in town without trying to conserve, it gets 15mpg. When trying to conserve, 18mpg. Hwy 20/22mpg.
