If it is an ordered out vehicle before the trip down there you can contact your own DMV and with a faxed bill of sale they will issue you a temp. Usually cheaper than one you will get in another state. Some states also give you credit on the temp against your plates when you return. Cash sale they don't collect any tax or registration. If loan they will call your state DMV and you may have to pay some of that up front then they send it to your state. Each state is slightly different. Tittle? if you are trading you don't even need your traded vehicle tittle. Just sign away that you own it. They will apply for a dup tittle on the vehicle you trade. ain't that scary? Never bought an RV in my home state yet.
