I know you asked about a tonneau cover but if you're going to be hauling around a bunch of bulky kid stuff, like stroller, play pen, crib, toys, etc, you might want to think about a cap. Even a low-profile cap would double the cargo space.

 

Gotcha. I think the seats in the SCab were only intended for hold car seats. Ever see any official release photos with the rear seat down? Lots of shots with neatly stacked work gear back there.

 

I would love one, but paying for baby delivery bill and I just had 2 surgeries in 3 days back in December... not looking forward to THAT set of bills. So the interm plan will have to be tonneau cover.
