These vehicle are built as an incomplete vehicle by Prevost. The conversion company then completes the vehicle, and issues the Title as a manufacturer. We have had success in California getting the year changed with a statement of facts, and an inspection. Your coach should have 2-placards, one from Prevost that will say that it is an incomplete vehicle, and a second from Techner showing the completion of the vehicle and model year. Every state is different in how they operate their DMV. I would recommend finding an independent Title company that handles vehicle registration in your state. They should be able to help you, and let you know if this will be possible in your home State. This is also a common problem that many other motorhomes have, including popular Class C models that are built on a incomplete van type chassis. Most DMV offices have a Vin decoder built into their computer systems, that will spell out the year based on the Vin number. They need to override this feature on these types of vehicles. Please feel free to call us if we can be of assistance (800) 460-7989.
