Not sure he would know -- However ever time the model year changes there do a OK to Ship usually within 2 weeks of start of build -- that is done to confirm no issues with new features prior to shipment
Got an update from a Friend at MAP --- My Blend date was 1/6 -- from WS 320220106 7942
It was confirmed my truck started in Body at 18:31:53 on 1/6 - no final rotation number yet - expect in early next week (takes 3 to 4 shifts from start to finish)
How close to your build dates did you see your window sticker ….. Dealer said scheduled for 1/6/22 build 🤞so want to see the sticker when it’s available
