2003 GMC Sierra 3500 Extended Cab 4dr Extended Cab 4WD LB DRW (6.0L 8cyl 4A)


Review

Truck looks great! Fuel mileage (non towing) is not bad for a ton dually at 13 mpg. Towing is another story. Six (6) miles per gallon is the average for this 6.0L engine. Tow mileage is terrible and the truck is at its maximum performance on the interstate at 70mph. It absolutely has no power left.


Favorite Features

Looks great, easy tod rive and quite comfortable for a ton truck with tow and snow plow features.


Suggested Improvements

Increase torque to allow easier towing and increase performance to establish better mpg.
