Mfg name on title of my Thor Citation
I defense of motor vehicle bureaucracies and insurance companies, VINs (Vehicle Identification Number) are assigned by the chassis manufacturers. The motors and stripped chassis are then bought by the coach or body builders. The VIN does not change and is the sole identification for the completed motorhome or specialty vehicle (ambulance, delivery, service truck, etc.).
The bureaucracies are using the only original identification there is, hence the designation of the chassis rather than the coach.
