Unfortunately, I'm not sure there is anyone on these forums will be able to provide you any real insight.
Based on the builds that people on these forums are posting that get picked for build, I don't really think commodities are the big limiter. Chips still seem to be a problem, but that's common across all trims and builds, so there isn't much you can do to mitigate it.
Your dealer's allocation and your place in line seem to be the biggest cause of delay. You can ask your dealer for your place in their line. They probably won't or can't tell you what their allocation is, but you can infer it if the dealer tells you how many they've delivered per month for the last couple. But that presupposes that Ford's able to pump out as many Broncos as they have been in Mar/Apr/May...
