I put a Extang Solid Fold tonneau cover on my daughters Dakota for when she went to college.. Yes it more $$$$$$ But I have seen pics of my kid with half a dozen other college kids standing on it at a larcross game.... I did add a aftermarket tailgate lock..


Here is a page with video... but look around I got mine for a lot less...
