I pull a custom made 5th wheel (48' Long... 24' with bunks for a boat and 24' up front with a custom made Lance Camper to fit the style of the trailer). I can pull the fifth wheel fully loaded (about 10,000 pounds gross) 65-70 MPH and get about 19-20 MPG. Before with the 460 I got 6 MPG and Could not even pull the dang thing. Cummins All The Way! :jump: Ford 460 = :td: Cummins 12v = :tu: |
The best I got was 18 on 37s with 5 speed, 373s, and it tuned stock, I'd average around 14. I haven't checked it lately since I hardly drive it but I believe I'm getting around 12-14. Could be closer to 10 though.
