Can't figure out if air ride suspension is standard or not on the 2015 SLT 4WD.
My 2003 Denali had it and its great when the truck is loaded up with people or cargo.
Is it only available with the max trailer package? I don't tow but frequently have lots of weight in the truck. Don't need the trailer brake option or the axel ratio.
