Probably worse than anyone else. lol Much of my driving is short trips and the terrain around here is pretty hilly and curvy. Average driving in the summer I get upper 18s. It will do around 20 if I go any distance. Towing the trailer (which is heavy duty) hauling a vehicle or my tractor (which has a loader and brush cutter) will knock it down to 15-16. Winter gas also knocks 2-3 mpg off of these figures.
I always manually figure mileage. This truck doesn't have the 'mileage computer'. My '03 Cummins truck did but I called it the 'liars board'. It would state my average mileage was 23 but figuring it manually the real average was 17. :wack:
Here's a pic of the '03 Cummins truck. 6 speed, 4.10 gears.
