We've got a tonneau on our 01 screw, and I hate it. Its really only nice to have if you aren't going to move ANYTHING or if you're going to fill up your entire bed. It's one of the canvas deals with the aluminum rails. It was good when we went up north and packed everything in the bed, but if you're only going to throw in the recycling or some groceries or pop cans or whatever, you might have to spend some time crawling in the bed to retrieve any lost items. I like mine, without the cover. Just throw my bags in the back and go, no problems. Just my 2 cents
