It depends on your body build. i'm 6'2" and my head is rubbing but I'm all torso. Some taller have said they fit no problem so your best bet is to sit in one and see for yourself. But for such a large vehicle, headroom is ridiculously low in my opinion.
The info is now on Toyota Canada web site. It looks like they all come with the moonroof which is a non-starter for me. Too bad, I was ready to trade my FJ for a TRD pro but the lack of headroom is a problem.
