Modifications that Change a Vehicle Registration from Commercial Class to Passenger Class
Vans (Part 106.3 (d)). You can register a van in the passenger class if the van has:

· at least one seat or set of seat fittings that is installed behind the driver, or
· camping equipment that is installed behind the driver. "Camping equipment" indicates that you have a permanent bed, a permanent stove, or a permanent refrigerator in the vehicle. If this equipment is removed and you use the van, you must register the van as a commercial vehicle.
Pick-up Trucks (Part 106.6 (c)). You can register a pick-up truck in the passenger class if the pick-up truck complies with all of these requirements:
· The pick-up truck has an unladen weight of more than 5,000 lbs. and is used for non-commercial purposes.
· The pick-up truck does not have any business advertisements.
· A permanent camper top completely encloses the truck bed, and which has one or more side windows.
· The pick-up truck has seats, seat fittings, or permanent camping equipment that are installed in the truck bed. "Camping equipment" indicates that you have a permanent bed, a permanent stove, or a permanent refrigerator in the vehicle. If this equipment is removed and you use the pick-up truck, you must register the pick-up truck as a commercial vehicle.
