I would call up your local DMV or appropriate state department and ask them what to do. Most states allow you to pay a small fee and show an out of state status and they will issue you a temporary paper plate for the vehicle to be relocated. You should have no issues transporting the truck across state lines to get it home this way. Just make sure the title is transferred to you so you can register it in your name and in your state.
If you have any other questions, don't hesitate to ask
