Passenger-van fitment is the compatibility of equipment with the exact vehicle, its occupants, and its existing systems. A seat, step, rack, partition, or other accessory can appear to fit the available space while using the wrong attachment arrangement, obstructing an exit, interfering with safety equipment, or adding more weight than the intended layout allows.
Good fitment therefore requires more than a model name and a tape measure. Identify the vehicle and equipment precisely, check the supported installation, and assess the completed arrangement. Seats and passenger-access equipment deserve particular care because their attachments and surroundings are part of how people use the van.
