so what is the highway mpg on a 5.4?
I am looking for a new truck and I have been looking at the 08 F150 but I found a nice 08 ext cab long bed superduty with a 5.4 and 410 gears, and the 5 speed auto trans. anything is better than what I had. A 97 F250HD reg cab long bed, with a 5.8 and 3.55 gears with 33's. almost 12 mpg hwy.
