LOL. This truck will never see 30mpg, although I must admit it is far better on fuel than I would generally think. The Instant MPG always shows 0-30 and there is like a bar graph that fluctuates on the graph based on your instant mpg.
Yes, it's the 6.7. Why the 450? Mostly because of the wide track front end, amazing how much difference 6 inches makes when trying to turn around, greatly reduces the amount of room you need. Why Ford? Seems like they have made the greatest improvements in their trucks over the years, yes I'd love the tranny from the GM line, but the Ford seems to have the greatest lifespan, and when you get a truck like this you hope to make it your last. ONLY real downside is the stupid Exhaust fluid, has to be refilled far too often for my liking (actually just having it kinda makes me mad, but whatever).
No load, it gets between 16-20mpg. Pulling the dove tail it drops to around 12-13mpg. Pulling the 5er it seems to stay between 10-13. (I expect to probably see 6-8 pulling through the mountains, haven't really pulled anywhere that wasn't mostly flat thus far)
However, you'd never know you were pulling a trailer by the way the truck pulls, the 6.7 is a strong motor, hopefully it proves to be long lived as well. The built in exhaust brake is another plus IMO. Set it in 5th gear going downgrade and never have to touch the brake to keep it at 55-60mph.
