I suggest going to this link where you can register and input your vin. This will give you insight on how your truck is progressing through production. At some point, you can also pull the window sticker as well as register your truck in the Ford Pass app. Once it is built, the Ford Pass app will show you the location of your truck, typically updated every time the vehicle is started.
You should get an email from Ford with a build date, and once you reach that date (assuming it hasn't gotten pushed back like others have experienced), production typically takes a week, maybe a few days longer if they have to send it off site for things like the spray-in bedliner, wheel well liners, etc...
