I got my truck last week. Ordered also at the end of October. Crew cab 6.2, standard bed, SLT premium plus, and 4wd. Took a few weeks for the order to get accepted. Dealer had the allocation to get the 6.2. Getting built wasn’t that long but when it came time to ship that was a different story. Was scheduled before Christmas to arrive at the dealer. Then got pushed back to right after New Years. Signed the paper work since the dealer had a confirmation on delivery date. Then it came in twelve days later. I wanted the AT4 but my dealer said they were on restriction. Now my dealer said that GM is going to put the 8speed in more of the GMC trucks that match the Chevy trucks since the ten speed is getting hard to come by.
