I have the 1500 ext cab 2wd model that includes the 5.3 l v-8 with management. The truck gets 26 mpg on the highway! The average for the truck with over 6000 miles city/highway is now 20.6!

With the specific gears I have in my truck, I get 20+ MPG on the highway...and I have a crew cab truck. City mileage is right in-line with the EPA of 14, but it is no worse than the others.

The 5.3L gets an impressive 20mpg on the freeway and with a tonneau, about 21. Mixed driving is about 15-17mpg and purely city driving nets between 14-16mpg. Towing economy is not bad at about 12-13mpg with a light load and 9-11mpg with a heavy load.
