We have a 2005 starcraft travelstar 21sso hybrid and on the front tent, in the top corner, it has come apart from the frame. The canvas is in good shape, with no cracks or holes, it's just this corner that has opened. It seems a shame to replace the whole thing, since there is nothing wrong with the canvas. Any idea how this can be fixed? We don't know too much about campers. Thanks in advance. I included a photo of the hole.
