Now have a 1999 F550 crew cab dually with pickup bed and 7.3 powerstroke.
Milage for a 2 ton truck with Dana 135 rear end and 4.88 gears. 12.5 MPG all city driving and 15 MPG at 70 on hiway. That is empty.
Loaded 12 on flat and 10 to 11 depending on how many climbs it has to make.
Holy Fuel Economy, Batman! How do you get 15 MPG? Truckasaurus gets 12 MPG highway and 8-10 towing. She's a 2003 F-450, 7.3, Dana 80 with 4.88 gears. I'm envious... Share your secret with me before I go broke buying fuel!
