Fuel Mileage?
Guys I have a 99 F-350 2WD 7.3L, auto, crewcab duelly cruise control on, 4" wide open exhaust, small motorcycle trailer, only 1 bike half of the trip, 450 mile round trip, 65mph/2100 rpms. I got 12.5 mpg? Is this what I can expect?

That sounds low to me. I get better than that with my 2 WD V10 (3.73gear). From what I have read in this forum and the diesel forum, the 7.3 diesel is the most economical of the two Ford diesels. From your mph/rpms you must have a 4:10 or lower gear . I run about 2000 rpms @ 70 mph. The lower rear ends really affect your mileage. Did you just get the truck or is this your normal mileage?
