2008	4dr Extended Cab 6.5ft bed 315-horsepower 5.3L V8 4-speed automatic RWD	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!

2006	4dr Extended Cab 6.5ft bed 295-horsepower 5.3L V8 4-speed automatic RWD	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. see full Chevrolet Silverado 1500 review
