what kind of delay times are you talking about?
sure the supply chain problems today are causing some issues but not totally.
usually dealers do not keep in stock all models, they usually keep certain popular models with either basic features or a couple in stock fully loaded. Some customers want specific features which makes the mfg and delivery times more extended because of the special orders they make. From my experience when customers order trucks if they are not stocked at the dealer then the wait times can be many months, those are the orders that are built when ordered and of course the more orders there are the wait times can get rather long because they use the process of building them in the order they come in. Nobody gets any special privilege's to jump the line in front of others.
