As mention earlier get the order # then go to GMC/Chevy website and click on "Chat now" and select "Checking the status of my order". An agent will come online and give them the information.
I ordered mine 2 weeks and I'm at 2000 "Order accepted".
I hope I get mine soon as well to take the family on a ski trip to Mammoth.
