I was informed that all Denalis come AWD standard, however, I just read that that's not true starting in 2008 they offered 2WD and AWD. I was told I could tell by looking at the front axle. I've attached pictures. Can someone verify if it's AWD or 2WD? Also, I did the vin thing (checking if the 5th letter is a K or C) and it's a C, so I'm assuming again that it's a 2WD.
