I own a 2010 F150 with the 5.4L. It just kicked over 188,000 miles. I bought it new on July 1st of 2010. Had to rebuild the limited slip in the rearend at 110k. Did plugs at 125K. Had to replace an O2 sensor. Change the oil every 5K and rotate the tires every 5k. Only put brakes on it once. I am on my 4th set of tires due to the amount of miles I put on it. Still running strong and still looks good except for a little cab corner rust. Overall been very pleased.
