Now have a little over 1400 miles on my 2012, regular cab, 4x4, manual transmission. I kept speeds pretty low, below 60 most of the time and drove backroads instead of interstate for approximately first 500 miles. Now driving between 60 and 80 on interstate for 90 mile round trip to work. A few miles is city.
First few fillups were 24+ mpg. Tonite filled up on way home and mileage is up to 25.43.
I am happy with 25 mpg. I would like to put a topper, probably leer on the truck.
What kind of change in mpg should I expect with a topper ?
