Well looks like SM05 and I got the same email with the build date getting closer.! Same is true with the Order Button and Yes SM05 looks like the exact BS BL build!Just got an email update from Ford with new and earlier build date - from June 28th to June 21st. I'm not complaining but considering 2 week production shutdown and chip shortage I find this change's direction strange. Like I said, I'm not complaining.
Edit: just noticed that last email includes new Track My Order button. That's definitely new development. I can see my order details there, etc.
Ordered on 3/1/21: Cactus Gray, Badlands with Badlands package, tow, Copilot 360 Assist+, Cargo Mat, Cargo Management System. And the block heater.
