I have owned this truck since new in 2003. Only in the last several years have I used it to its full potential. I have pulled a 10,000 lb fifth wheel to Florida twice and a new 12,000 lb fifth wheel to GA last week and I averaged a little over 13 mpg. On the return trip I got over 24 mpg running at 70 mph all day. I do have a tonneau cover for the bed which might help. I first took this new truck to Ohio in 2003 and only got 22 mpg with the same configuration. I did add a K and N air induction system before my last trip but this truck pulls like a champ without any additonal brains or Banks kits. The 5 speed transmssion is smooth and I know improvements have been made in the 09's.

this is the fifth (sixth if you count my Tahoe) gm truck that i have had and it is by far the best. talk about reliable. a heavy duty truck that has no problems pullikng my triler in any clime and place. in the snow, on the beach, it does not matter. talk about space, i have two kids and a dog and we travel with no problems, even on long trips. i will never own another type of truck, from any dealer...now a hummer...that is a different issue. ron tootle major, us marine corps camp lejeune nc gm truck owner since 1985 1985 chevy s-10 1988 chevy s-10 2001 chevy silerado ext cab z-71 2002 gmc sierra ext cab z-71 2002 chevy tahoe 4x4 2004 gmc sierra 2500hd quad cab 4x4

This truck has been used mostly on the highway, carries dirt/mulch and recreational toys. And has done so for 62,000 miles without a single mechanical problem! It was originally purchased for towing a camper. Within 6 months of purchase, rising gas prices made driving this thirsty vehicle downright painful! With the cruise control set at 65 station to station on an interstate,13.7mpg. Disappointments? The ventialtion system. The AC is not cold nor dry enough to defog windows. And the radio is horrible! Did I mention fuel efficiency?
