I threw the Yakima Mega-warrior basket w/ extension on my roof with their spare tire mount to free up space in the back. My 31" spare didn't fit very well in the back and took up way too much space and also causes a blind spot. On the basket its out of the way and doesn't limit vision. Others here have mounted factory tire swings on the back because, if I'm remembering correctly, its braced for it already. The hard part is finding a swing in good shape.
