Yeah, my dealership definitely has allocations -- They've already received at least three Raptors that I know of, and I think they have a 2019 or two on the lot.
Part of me thinks the dealership might be pushing other orders ahead of mine, since I did negotiate off MSRP and others may not have. But ultimately I tend to just believe it's either a parts shortage (Recaros) or Ford is slowing down builds due to excess inventory. Though the latter wouldn't explain why my order has been bumped so much yet others are getting built fairly quickly, hence asking about your order details.
Hope you have your truck delivered soon though. Ultimately, mine will be built when it's built and outside of rabid anticipation, I'm in no real rush.
