Cannot compare with so many differences in load carried, speeds driven, elevation gains, and even wind. On a trip last year cover 3000 plus miles up to Yellowstone and back through Utah and into California I averaged 13.5 MPG with a diesel and with a 3700 lb. load in the bed. Recent trip through eastern sierras up Hwy 395 with 4000 lb. load in the bed and dealing with a lot more wind and more elevation gain in total the MPG was 11.1 for the 1400 mile trip.
Wind is the biggest factor. On legs I drive frequently, if there is a 15 MPH head or cross wind the truck's gas mileage is reduced by 25%.
With the high price for diesel fuel (usually about the same or more than premium) and the more expensive initial cost and maintenance costs one should not go with a diesel engine in the misguided belief that they will save money doing so.
Oh now come on.... one can't put a price on having all that extra torque. ;)
