I'm thinking it is the scales, maybe BAP. Plenty of Lariate Ultimates being delivered with all of your other options. I think the scales are what is holding up KR+ trims from getting scheduled.
Ordered 10/29, Platinum 7.3l priority code 10. Spoke to my dealer yesterday to start planing for a MY24 order. They're pretty frustrated at Ford as the vast majority of their sales team focuses on retail sales and they can't get the trucks in that retail buyers want.
At this point, anyone scheduled will likely be an August or September build date and the end production at the beginning of October so not much time left for people to be scheduled.
