Overview & Reviews
The Sierra gets a revised look this year that includes a new front fascia, revised side moldings and optional multifunction, fold-away mirrors. On the inside, GMC has added new seats, a more comprehensive driver information center, a redesigned instrument panel and optional dual-zone climate control and satellite steering wheel controls. On the hardware side, the standard 6.0-liter V8 gets electronic throttle control as well as the ability to run exclusively on compressed natural gas (CNG) or a mix of CNG and gasoline. Other upgrades include an improved Insta-Trac part-time four-wheel-drive system for reduced service costs, a more efficient starter for the 8.1-liter V8 and a revised headlight switch that allows drivers to turn off the daytime running lamps.

Great Truck - 2003 GMC Sierra 3500
By tdorsett_1 - December 2 - 2:00 amHauling hay and horses has never been so easy, power to spare, better on fuel mileage that I would have though. Pulling a small 2-horse slant load trailer with two 1200 lb. horses or a twenty-foot trailer loaded with three round bails of hay, I get an average of 18 miles per gallon. Without pulling, I get between 21 and 25 miles per Gallon. (Highway)
