I wouldn't buy from CVT again. It arrived damaged and they told me I could either send it back or just deal with it. I honestly thought they'd give me a hundred bucks off or something and I would have been fine with that. Oh, and the metallic accessories on it are all getting a little rusty already. I'd recommend the roof nest because it's the same design and the same Chinese company makes it anyway, plus their customer service is better from what I hear.
I'd recommend RCI all day though. the rack is sturdy and they make adapters so you can run a tunnel cover. I'll actually be transferring to an RSI smartcap instead, but not for any thing being wrong with the rack. Do you have a carbon pro bed?
