Abstract: A recreational trailer with a monocoque body mounted on a chassis. Modularly interlocking and adjustable construction segments are mechanically fastened forming a monocoque body. Each component of the present invention may be individually altered to adjust the dimensions and/or functionality of the recreational trailer. The recreational trailer may be altered by resizing various panels to create different embodiments of the recreational trailer that are longer and/or taller and shorter and/or smaller. The various panels may be integrated and locked together to form an integral structure.
