As my truck gets more mileage on it I am liking it more and more. Another quick camping trip over and I am continually impressed with this pickup. Not quite 300 miles this trip, almost all flat 55-65 mph. Increased lifetime towing mpg to 11.6, in my opinion amazing for a gasser 3/4 ton towing a 28' 7500-8500lb trailer depending on what we are taking with us. Previously the best mpg I got was with a chevy 1500 with the 6.2 at about 9 mpg.
