I think the forum magnifies the issue a bit as those who are waiting tend to be the most vocal about the wait (myself included). Look on Facebook and you'll see quite a few people who ordered and received their trucks. Some even placing orders in April and taking delivery in June. Are they ordering Tremors? Most are not, but I've seen quite a few XLT/Lariat (even fully loaded Lariats) get delivered - some with orders placed well into the Spring. You'll even find quite a few happy new Tremor owners on there.
You'll hear the most frustration from people like me who ordered King Ranch/Platinum/Limited trim as Ford has not been able to produce many of these. It is likely a combination of several factors - supply chain still being an issue and Ford catching-up on fleet orders so they don't lose the massive government contracts to GM. I expect it is more the latter as many of the "constraint" items have been showing up on the fully loaded Lariats that are getting made (e.g., multi-contour seats). To your question about profit... the total profit on the hundreds of thousands of XL/XLTs that they produced probably outweighs the incremental gain that would get from the few thousand KR/Platinum/Limited orders. Those fleet orders and XL/XLT work trucks are the cake, the others are probably just icing for Ford and I don't seem them shifting like GM has to prioritizing higher-end / retail builds.
@Alpoba 's recommended approach definitely solves one major challenge - dealer allocation. Multiple orders won't solve any issues related to constrained items (i.e., if you have ordered a - fill in the blank trim or option - and Ford is saying they've exhausted those for the week/month/year, doesn't matter where or how many orders you have placed).
