Replacing an old competitor cover. The truck is a short bed tundra sr5 with a 2002 crew. Note that the tailgate is down, the mirrors are down, and the antenna is removed. The size of this case is L (212-228 inch). The case fits snugly and even during a thunderstorm with gusts of wind, it stayed in place without the straps. 6 layers? but was thicker than the old paintwork, feels like an underlay, so must not damage the paintwork. The lid fits the width of the truck exactly and is long enough to close the back door, allowing water to flow back and not filling the truck bed with water. While I'm happy and will update the review, do repeat.
