We purchased the F150 5.4l v-8 for its powerful towing capability. We tow a travel trailer that weighs in @ 7200lbs. dry/wt. We have the 2wd SuperCrew with auto transmission. We live in northern California and the F-150 Triton 5.4l v8 has no problem at all pulling over Donner Summit or over the Siskiyou Mountains into Oregon. The ride is very comfortable, for I am 6'4" and I not small in stature, and the handling is smooth. Very road worthy when pulling the trailer. I am very satisfied with the overall performance and comfort of the F150 SuperCrew. The mileage when pulling trailer in cruise control @ 55- 60mph range in overdrive is around 11- 12mpg. Not pulling trailer about 17mpg, not bad for a truck.
