I found this tonneau from Pace Edwards. It is the Jack Rabbit Style roll top. I needed to modify the back rails slightly so that I could keep the spoiler. Roll top covers inherently leak. I found a couple of spots and think that I have cured them. I do still get very minor leakage at the tail gate. This is because of the BedRug. The top can not seal against the painted surface. I am thinking about getting a top cap for the tail gate to cover the rug and give a smooth surface to seal against. I have pics. Let me know where to send them.
