Something is screwed up. New vehicles do not have titles. They have a MSO. Manufacturer statement of origin. That has to be run through the secretary of state with dealership RD-108 PAPERS and then a title is issued.
Stop and think; In this day and age, most any document is easy to counterfeit. With a counterfeit MSO, some counterfeit dealership paperwork and a 'new' vehicle, there is no record for the prospective owner or bank or license facility to find to indicate anything out of the ordinary. Stealing the trucks in the first place would have been the toughest part. The states probably don't even check the 'hot sheet' for new production vehicles still on an MSO.
Ingenious bastards.
