I went with the BakFlip F1 with optional integrated BakBox. Love the cover, installation is a breeze, mostly water tight (little moisture in the corners), and it's rather lightweight yet durable. Installed the "Dee Zee tailgate assist" and "pop a lock" along with the cover to obtain power tailgate locking which is really a nice match with the BakFlip. Meaning with the cover closed and tailgate power locked (from the remote), it's entirely secure from the outside. A simple click of the remote to unlock the tailgate, open it and the Dee Zee lowers the gate effortlessly, and exposes the cover release if you want to open it up.
