Regular Cab Duallies
"RCD"
So, is there any reason I can't get the baby Duramax in a Yukon AT4? It is available in all other trims of the Yukon. So, it makes no sense for it to not be an option to have it in there. To me,this $900 upgrade is a MUST. So why can't I spend my money and buy it as an option? That means more profit for GM...
