I have a F250 6.7 Lariat crew cab with electric looking rear differential with 3.31:1 gears, Firestone airbags with a wireless controller. My son has a F150 XLT 3.5 EB 4X4 crew cab also with 3.31:1 gears. I get around 19 MPG, he gets around 22 MPG. His truck is definitely faster out of the hole.
I prefer the slower, heavier, more solid feel of the F250 diesel,
he prefers to drive fast and zip around.
I tow a 12K lb. 30 ft. toy hauling trailer with my Electra Glide in it with my F250. No way would I even consider hooking that up to his F150.
