Let’s hear your best MPG and driving style ?

I drive it like I stole it with our 40' 5.9 Cummins, hit 75 and 78mph and got 9.3 mpg pushing a small house down the road. My 5.4 Ford pick up gets 13 mpg driving it the same way, tho it lacks a bathroom, kitchen, queen bed, water heater, 90 gallons of water, a furnace, couple of tv's and a fully stocked refrigerator and bar.
It's all about perspective and what you're willing to put up with and or settle with. We're all different, and it's ok! Get out and enjoy yourself!
