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?

If a person is using the onboard fuel calculations to use for quoting fuel economy then they are delusional and kidding themselves. Not sure about other brands, but Ford wildly inflates the readings for MPG in the computer. My last 150 and current 250 both would show 21-23 driving flat ground, not towing, and an amount of fuel used. Bottom line it's off by about 10%. If the computer says I have used 18 gallons, it takes around 20 to fill. Haven't towed with the 250 yet enough to see what figures it tries to BS me with but I expect the 10% or worse reality.
Miles recorded by a reliable GPS, vehicle odometers are also unreliable, vs actual gallons used is the only way to check. Several fillups are required for any real time usable information. On my previous Ram 3500 CC 4WD dually towing a 15K toy hauler I would get around 8+-. One time in west TX with a 30 mph tailwind I got around 12. So I guess in the BS world I can say I got 12.
