I just wanted share my Roof Rack experience. The full roof racks have their uses and they look good, ext, but, on my newest LX I went with yakima bars instead. For me they are far more useful than the full racks, as my main purpose is carrying sports gear. I have the ski rack attachments, the cargo box and fly rod holder. I can swap them on and off quickly, and switch them between vehicles I currently own and when I sell a vehicle I keep the yakima/thule stuff and use it on the next SUV. Also, in my opinion, nothing beats a cargo box. It locks, it keeps stuff hidden, there's no need to tie things down, easy to access and its weather proof. A cargo box on regular old cross bars is just hard to beat for me. Plus the ease of installation and the fact that you can just pick them up at REI or wherever is great.
The only advantage of the full rack that I can see is the ability to put things like extra gas can, and propane, stinky trash (poop cans, please don't s*** all over the place people, pack it in pack it out!) ext up there. I have a rear bumper to store that kind of stuff. But yeah, I have had the full racks and I prefer cross bars.
