One question we get asked many times is, “How do I register my new cab?”. This is a fairly easy process that varies from state to state. If you don’t have an original chassis with title for your vehicle or Manufacturers Certificate of Origin (MSO), you need to register the vehicle as a “Newly Assembled” vehicle within your state of residence. MrC10 does not issue an MSO, but we do issue a Bill of Sale (your invoice) from us or the dealer that you bought the cab from. This invoice is considered an MSO by your states DMV (check your local regulations and laws). In most cases, the Cab Number issued by MrC10 for your cab will be used as or incorporated into the vehicle identification number (VIN) assigned by your states DMV when you register the vehicle.
