The no-third-row storage space and full-sized spare are among the points that sold me on the RAV. I despise donuts. Having a home for jumpers, tools and emergency supplies, while retaining the full interior space in its uncluttered glory is a huge plus in my book. I may end up sticking an amp and/or sub in there, either way, I have the option.
A split gate and top hinged glass would be a good compromise though. They could then have left and right handed versions, with a long section carrying the spare, and a short door on the curb side.
