Abstract: A composite commercial walk-in van body is constructed via lightweight, composite structures. A composite floor structure having integral logistic tracks are joined to composite sidewalls that include integral rub rails that also integrally formed logistic tracks on an interior thereof. Pigment molded lower body panels that extend beyond the sidewalls are fully replaceable to enhance durability and maintenance of the walk-in van body. A one-piece molded roof eliminates leaks. Any necessary rivets are captured so as to prevent any wet-to-dry surface penetration. An easily accessible washer fluid and brake fluid reservoir aid in the maintenance and operability of the walk-in van body. Such elements contribute to substantial weight reduction, and increase in durability, functionality, and fuel economy of walk-in vans utilizing such a composite body.
