AC cab filter GMC vs Chevy

[02_2500hd]

I keep seeing on the window stickers on the Chevy's saying AC with Air filtration system, but never on the GMC's. I haven't looked at my GMC yet to see if I have the option, it was listed on the sticker under the AC option, but then I've never seen it on any GMC's. Is that something standard on the GMC's or what???

My guess is that it is standard on both trucks with air conditioning.  Chevy is just trying to talk it up a little more than GMC.
