Welcome.

I'd say it's a personal preference as to where you haul your stuff. Looks like a nice clean mount inside, but it takes a lot of space.

I use a Yakima roof top system for my bikes, kayak, and skis. Usually, after engaging in one of these sports, I'm looking for a place to take a nap, and none is better than the back of my X5.
