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.


Best Features

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


Worst Features

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