2003 GMC Sierra 2500HD 4dr Extended Cab SLE 4WD LB (6.0L 8cyl 4A)
2003 Sierra with 8.1 liter 345 HP and Alison Auto. Plenty of power for towing. A little hestitant on take off when cold. 20,000 miles in 6 months and it runs like day 1. Fuel mileage is absolutely HORRENDOUS!!!! Towing an enclosed race car trailer x-country avg. mileage = 7.95. Driving enmpty no load at all avg. mileage = 12.98.
