towing mileage of trucks
Does anyone have a range of MPG for a F-450 dragging a 18,000- 21,000 5er? is it much different from Ram 3500?

I'm going to put my 2 cents in here. On my Dodge, I put 19.5s on it and had a slight gain in fuel economy when driving down the highway and towing. I had a slight drop in economy around town, they are heavy, but have less rolling resistance. There are a lot of factors that go into economy and engine efficiency is a big part. Blanket statements will surely get you into trouble.....Just my experience.
Did you calculate your mileage based on actual miles clocked, not what the odo showed?
Many different methods to check miles per gallon but only one way is correct. I have been shocked with some of my friends telling how they check mpg. Good old gallons into the miles driven, the old fashion way as Cummins does.

Speedo was re-calibrated and confirmed with GPS. So yes it is Accurate. Truck has 33" tires on it. It also has an Allison transmission. The gearing is 354s and the cruise RPM is around 1600-1700. The truck gets around 24-26 MPG on the highway. If I drop the speed down to 55 it jumps to 28-29.
