Wow, 7 pages of discussion about ratios. Guess I will just keep my '04.5 5.9L 325 HP 600# torque,3.73 ratio truck with 210K and counting. I tow 19-20K combined at 65 MPH and 1800 RPM on the interstates or two lane roads where allowed at 10-11 MPG. I mostly tow from Indiana to east of the Rockies, west central Montana. Current trip has taken us from Montana thru the Black Hills into Colorado and on into eastern N.M. I have towed from Utah on I-70 to Indianapolis with this set up and not worried. Current trip will take us across TX, Ok, to Tn., to southern ILL, to Indiana on US-50 to home. Oh, the best part about the truck is it has been payed for for years. Good day ye all.
