How Do I Tell If My Denali Is Awd?

Look in the glovebox for the rpo list. Look for NR3 or NR4. I believe one of them is the RPO for the Borg Warner Case.

Not only that, but the OP hasn't been on here since Oct 2015

So I know this is an older post but I’m looking at a Denali truck and I found a 2012 has AWD and a 2015.  Which one would be best to go with?  It will be fir daily driving, and down the road for towing a small trailer. 
is it better fuel economy with the AWD in the 2012 year?   Thank you!

For all you so-called experts here, if it has a front diff or front axle shafts, that does not mean it has AWD! That means it has 4 wheel drive, not necessarily AWD. It could be either. So having your wife look under the front for a diff, would not answer the question. Stop being a nasty know-it-all when you really do not know what you are talking about.
