4300 Interim Transfer means what the dealers are saying. On a rail autocar some where in these United States. Once it gets to its destinatation rail yard and is off loaded it takes at least two days to get dispatch to assign a truck, then however many days for the carrier to make its rounds from dealer to dealer until it reaches your dealer.
Status 3300 is parts are being assembled from around the plant and its suppliers. You are close but no cigar, which is 3400, at which stage a target production week is announced, and the TPW is one to two weeks after the 3400 date. The vehicle is almost always assembled during that week - 00% certainty. But from 3300 to 3400 can be a day or a week or more, the time is very parts availability dependent.
Hope this helps that last few posters.
