Your big diesel truck's bed is one of its most prominent features, but you probably don't want it open to the elements or prying eyes. TruXedo's lineup of high-quality, roll-up tonneau covers are the perfect way to add a layer of security to your bed while still getting complete access to your truck's bed. TruXedo's roll-up tonneau covers open and close through a rolling action, and tuck against your truck's cab when fully open which gives you full access to your cab while still keeping your rear windows clear. TruXedo has Duramax tonneau covers, Cummins tonneau covers, and Powerstroke tonneau covers available in several different designs and styles so that you can find the perfect roll-up tonneau cover for your choice of diesel rig.
