Do you have a VIN?
Did you get a VON? if that is the term.
Once in build, you can input your vin for a build sheet.
If your dealer has slots available they can place the order for your truck, I began an order process in August with dealer #1, he quoted me jan. delivery. I contacted dealer #2, he stated 8-10 weeks. I went with #2 and he was good for his word, got the truck in 8 weeks.
If you can input your vin and get a window sticker, that means the dealer has paid for it and it has moved on to its next location, or is being shipped. My truck came out of the Detroit hub, it was 3 weeks from ship date to arrival at the dealer. If your salesman is not giving you any good information as far as ship date, then you can call FCA and they will give you updated sketchy information such as in production, or it has shipped, not any more help than what you may have but worth a try. All of the places to "input" different numbers are up in the sticky section. Hang in there.
