Hello agin all well I traded in my 2005 gmc sierra for a 09 gmc sierra love the truck it feels so much higher than my 05 love the interier and so on.eny of you with the 07 and newer trucks tell a diffrance with fuel milage? I guess the truck has dod 4 cyl to 8 when needed I cant tell when it kicks in and out pretty cool. Also the gas peddle feels a little more stiff than the one in my old truck I wounder if thay went back to a cable throddle. Eny way so far so good.
