This is my first GMC Truck. I was
happy with the over all performance
with the 5.3L motor. The large fuel
tank will take us about 490 miles on
the open road about 19 mpg as long as
you keep your foot out of it. That is
great my suv with a V6 3.2L only gets
18 mpg and is much smaller.. So buy
with Confdince. but try to step up to
5.3L motor you will be glad you did..
