I think it changes everything. You have a VIN means you have a build date, with that comes certainty. Even if that build date changes by a few weeks or a few months, you still have a good timeframe for when your truck will get delivered. Once something is certain, the wait gets a lot easier.
I said this before, for me there will be two happy moments; truck gets a build date and truck gets delivered.
I, for one, really don’t understand all the constant non-stop checking going on this very thread tracking minute by minute progress, trying to decipher window sticker codes and calling rail companies trying to see where the truck is. What a major waste of time and self induced anxiety trips. One can’t change a damn thing anyways, why punish yourself with useless half knowledge.
