Gas mileage last trip.
Total weight 12,380 lbs.
From home to where I camped was 88 miles and the last 26 miles was graded gravel road.
I gained 3300 ft from my doorstep to where we camped.
I ran in 4-low for about the last 10 miles. The truck would shift all the way into 5th gear at about 30 mph.
It helps cut back making the washboard worse and its a lot easier on the truck instead of pushing it in 4-high.
9.1 mpg round trip. I'm happy. ;)
