Don't want to get your hopes up, but it seems that the estimated delivery date when the truck goes into production is typically LATER than after the truck is shipped.
For example, when my truck was in production the EDD was 12/26. Then when it was listed as complete, the EDD went to TBD. Then once shipped, it went to 12/16. I expect it around 12/13 from looking at CSX transit times... But I could be wrong.
I've read several other posts that lead me to believe this is common, but would be interested if anyone has not seen this pattern with their orders.
