Howdy. So I saw a thread on Facebook where someone's dealer mentioned that Ford is out of tonneau covers, and then I just got a call from MY dealer who said exactly the same thing.
But she actually went so far as to say that my truck was still not even "scheduled to be scheduled" as long as the tonneau cover was still on the build, so they removed it the other day. Hoping I get a build week tomorrow at this point.
It's not 100% proof that that was why I'm unscheduled so far, but it's worth checking. That's an easy (I think?) after market add to be holding up my entire build... might want to look into it if you're still waiting, too!
