I ordered my 2021 Sierra AT4 crew cab standard bed on 10/8/20. Truck was built 11/10 at Silao. Since then, its been at status 4000/4B00 and hasn't moved. I'm in North Carolina. I'm wondering that takes so long to get this thing on a train and on it's way to me. For how many trucks they produce every day, it makes no sense why they'd hold on to one for so long after production. I've tried asking my dealer but they've been no more helpful than the GMC chat people. Dealer originally said 6 weeks, its now been 9 weeks and no end in sight. I was really hoping to take delivery by Christmas with all these great year end incentives, but with a 2 week ship time, there's no way I'll see it before year end. ?
