I bought the Skybox 12 in fall 2008 & mounted it on my Subaru Forester. I love this thing so much. There is plenty of space in the 12 for 2 snowboards, 1 pair of skis, 3 sets of ski poles & other random stuff like shovels.
One of the things that hooked me on the Yakima was the fact that you could mount it on either side. I have mine mounted as close to the driver side as possible. Works great.
The locks & latch system are simple to use. The box lid stays in the up position when loading/unloading. Doesn't seem to hurt gas mileage too too much. Quiet on the road too.
All in all a fantastic product. Money well spent. Go for it
