As much as I don't want to buy a new truck...it's time lol.

W truck looks better no badges how u get them off with out messing paint up I want to takem of mine thanks

Had an 05 Ford with the 5.4 ,stock the milage was horrible. Changed the intake and air filter,exhaust ,and added an Edge Evolution programmer. After all this Best on hwy was 18 and avg 14 . Put a trailer on the hitch ,instant drop to 10 or less.
Got a 2010 now and stock gettin 18 on Hyw avg 15 around town.

My 2009 and father's 2009 both get around 19 to 21 on hwy if in cruise overall avg 19.7 mpg.
Towing I do drop to around 16 avg which still good for full size trucks.
My 2010 dodge with hemi I use for work gets the same.

Ford Trucks never have been known for getting good gas mileage.
Inline 6 was a strong engine, but worst gas mileage you could ever ask for.

Biggest hangup I have with Ford is they chased all the good tech's away and left with alot of tech's with limited experience.
I am glad I left before they lowered the rates they authorized for warranty work.
At one time they had experience tech's that were loyal to dealers for years leaving in masses to go to private shops.

Second biggest issue is on the F-150 engines I hate changing plugs due to thin head. I did a few of those for friends and got soak the plugs down overnight, use special tool, and still watch out not to strip the threads. You would have thought Ford would have fixed this.
