@MadDogDelpho , you are correct on the windo good sir! @willthom , in addition to the rear window, I can also tell by the chrome tip of the exhaust kit and by the onstar/xm antennas on top. The 2005 and 2006s just had the smaller circle shaped exhaust end. But you have the little square xm antenna over your passenger side, whereas my 2006 doesn't have that. In 2006 is when gm did away with the little square and put it somewhere inside the truck and gave the trucks a little shark fin style antenna over the drivers side and nothing over the passenger side.
