I have the tonneau cover on my Baja. Between the cab and the bars is a hard plastic piece that's held down by two screws on each side, with some weatherstrip against the cab. The soft part wraps around the bars with velcro, and the soft part comes all the way to the back. I think there are more screws to hold down the pieces that the soft part attaches to, which also means that you can't lower the tailgate while the cover is on, you must undo it. It's a decent fit, though the hard plastic piece between the cab and bars concerns me because I'm not sure if a bike tire can fit up under there yet when hauling bikes.
I also have the full front bra, and I'm liking that quite a bit, the fit is really nice.
