This was to replace a canvas covering on my " covered wagon " style on/off road camper that I made out of an old small utility trailer. The canvas did hold up to 70 mile an hour freeway speeds ( the top is actually three layers with the top layer being canvas with extra grommets ) But , after two summers the canvas broke down so I replaced it with this heavy duty nose tarp. It fits perfect and looks like it will hold up to the elements for much longer. I doubled the number of side grommets on the nose tarp as well as folded the ends under at the ends about a foot, gathering the ends tight over the front and back ends of the frame with a rope in the folds , like I had done with the earlier canvas. Freeway or no road at all it works awesome . I am thinking about making more of them and selling them.
