Do some searches on this topic. There are lots of discussions on this. I have mine mounted outside on a swing away tire carrier. I got the one that locks and has the drop down arm. It really doesn't block that much back window view either. It blocked more when it was behind the seat.

Yes, it's a pain to open up when you just want to throw something in quick, but the extra room you have is well worth it. I have the full bench 3rd row seat and can fit 3 kids back there. If you haul a lot of stuff you will like having the extra room.
