Let’s hear your best MPG and driving style ?

Actually, I wouldn't know, whether car, truck, or when RVing, just never felt the need to track mpg. All our vehicles including motorhome have mpg tracking feature along with the couple of scangauge 2 modules mounted in our HD truck and class A. While I monitor other pertinent powertrain parameters, unless I see a significant change in fuel demand it is rare indeed for me to consider mpg, just pull up to the pump and open my wallet. Driving habits are typical, when RVing I stay within 5mph of posted speed limit, with daily driving I roll at 5 mph above speed limit.
