Miles and Kerry have outright said that they, along with Monty, planned out the entire story for the series, before they even began writing the script for Volume 1.

They had already thought about what Dust should be by the first episode. The White Trailer was when they were working out some of the details about Dust - whether it should be color coded, what all it can do, that kinda stuff. I'm sure they had worked it out by Volume 1. They did say that but also keep in mind that while they made the whole storyline and plot it doesn't mean that they have revealed everything just yet.
