This is how my POC was as well, no ship date.
Bug the dealer for updates (FCA communication seems worse than the bad dealer communication). I just checked for a build sheet every day, finally came up then the WS a couple days later.
Figured shipping was soon and about a week later (Feb 7 2020) dealer called saying truck would be delivered on Feb 14th 2020. Stopped by today (Feb 19 2020) and found truck is in the state (CA) but not yet at the dealer, they say this week and I'm betting next week. Bottom line was I just checked for the build sheet, didn't worry bout the dealer and they didn't seem very interested in contacting me either (twice since I ordered, once to give me VIN and the other for the estimated delivery date). Wasn't a big deal to me, it will show when it shows, but that is me.
