Abstract: A self sealing potato truck loading dock is disclosed. This loading dock provides an effective air tight seal which serves to isolate the interior of a warehouse and the potato truck box from the outside air while said truck is being loaded or unloaded. This seal is accomplished by providing a series of double layered sealing canvases that encircle the entire opening of the loading dock opening. These double layered sealing canvases provide an air tight seal between the body of the potato truck box and the outside air by using a system of alternating slits in the respective layers of the sealing canvases and elastic bungee cords attached inside of the sealing canvases.
