 We have been leasing our F-150 SXT Sport 4x4 Supercab with the 5.0 Flexfuel V8 for two years now and overall we are very happy with it. Average highway mpg is 19-20 and local driving is 16-18 depending on the season. I do wish it had a backup sensor or camera. It is difficult to judge where the rear bumper is when backing since it can't be seen in the mirrors. My only other issue is that there has been, and still is, an annoying little vibration in the front wheels. I've had the tires rotated every 5K miles, the balance and inflation checked regularly, and the alignment checked. I'm told (not by my Ford dealer) that the  issue may be coming from having the 20 inch tires instead of the 18's. Overall we would give the truck a 9 out of 10.
