This GMC is way above average . Its a 4x4 with an automatic transmission and a 8.1 liter V8 engine . Our truck will pull a trailer and get fuel milage as good as a 6.0 liter . This GMC needs nothing . The tires are new , the spray-in-bed liner is clean and the interior is very nice . Our truck has bucket seats , power drivers and passenger seats and the A/C is cold . This truck has alot of life left in it . Don't spend $6000.00 more for a diesel that doesn't get any better fuel mileage when u consider the cost of diesel over gas !
