Looks like my order experience is coming to closure. This post is to only share my experience. I feel for those who are waiting unnecessarily and frustratingly long for theirs.
I ordered my AT4 (3.0L Premium Pkg., Desert Sand, Standard Bed) on 3/28/22. Wasn’t accepted by GM until early July. Was built the first week of August. Was told by my dealer it was not short anything needed to ship. Sat in Fort Wayne for over two months. VIN tracker never showed movement. Today (10/10) dealer calls and says it just showed up without any prior status update on shipping. Apparently is was trucked outside of the normal rail shipment from IN to the north east. GMC chat says it is still waiting for shipment hilariously. My dealer told me 6 months up front and it took 6 months and two weeks total so I am not complaining. But, I didn’t anticipate the difficulty of the long periods on not knowing anything or having any idea when things would progress.
