flattop49,
Just a note that whatever municipality issued the title you received from the seller technically had to use something on the truck to legally identify the truck. The missing ID plate could become an issue during your re-title process.
Regardless of any other folks experiences given, the only entity you must rely on for titling your truck is your own state DMV.
Your state laws and regulations are the only ones that directly apply, and that you must follow to satisfy the titling requirement. You should also be able to go online and read up on your DMV's requirements and rules that apply to title transfers and correcting title errors if such exist.
Good luck and let us know how your title situation gets worked out.
