Abstract: Aspects of the disclosure relate to passenger or cargo vans. Features include the structure and assembly process using a framing structure which defines and supports a rearward compartment. In certain embodiments, the framing structure can be formed as modular subpanels which can be easily assembled while also providing superior strength and weight characteristics. In certain embodiments, specialized joints are arranged to connect the subpanels. Exterior shell portions and optionally windows can be mounted to the framing structure to form a rearward compartment.
