Im looking at a 2006 F250 crew 4X4 King Ranch with the 5.4 V8 auto and 3.73Ltd slip. I was doing 50 miles a day to and from work and getting 14 to 17 mpg with my 2004 6.0 psd auto 3.73Ltd slip F350 crew 4X4 Lariet, very happy with the truck. I got a new job thats 1.9 miles from my house and Im sure it will kill the diesel with the short trip. Any body out there have experience with gas V8 in cc 4X4?
