That was me and two passengers, no cargo. I just drove to Denver and even coming through the mountains my MPG's improved to 13.6. I've got around 800 miles on the truck now and will be interested to see how it does on the trip home with the Norweld tray installed. I suspect that as the motor breaks in it'll improve a little bit...at least until the camper goes on full-time.What kind of weight in the truck during those trips?
Was that loaded or empty?
