swiss trailer canvas

#1
O.K. all you trailer experts,

The swiss made a one ton trailer that had a canvas? cover that had rpoes for tie-downs. The one ton is 96' long(inside the bed) w/ aa arched roof. I am looking for a source for the canvas cover preferably stateside. A picture can be seen at : www.swissarmyvehicles.com

Any help would be appreciated. Dean
