Will these things be adjustable across the length of the roof rails are are they fixed in a single location? Can't see on a Murano where they would be able to slide. I'm thinking that regardless of availability, I may just stick with Yakima for price, versatility, etc.
They are definetly fixed. You can see where they would mount on the rails by finding the screws on the inside.
I love my Yakima LowRider rails, they are a little more expensive than the Nissan ones, but they are adjustable, and easy to put on and remove. The Nissan ones looks like they would take a minimum of an hour to install/remove as they are screwed into the rail.
Personnally I think the Murano looks better without crossbars, which is why I like the Yaks. Most of the time they are in storage, but I can put them on in 5 minutes whenever I need them.
Up here in the frozen tundra, we've had the cross bars available for some time, although not the "Nissan" cross bars like these -- they're Nissan-badged Yakima bars. Granted, they're not as integrated as these, nor are they that sophisticated in terms of their mounting hardware, but they are adjustable and removable. To me, this is an important feature -- I only install them when I need them. Others on this site have installed some Thule bars and they look impressive -- also adjustable and a much more modern-looking mounting system. Of course, they're also about twice the price.
Hey - My crossbars just came in and I was able to install them last weekend. They look nice but not as beefy as I had expected. The install was a breeze.
One unexpected benefit though - the wind buffeting when I have my sunroof open all the way is GONE! It used to be that I would only open my sunroof 3/4 of the way when driving on the freeway but now, I can open it all the way and no problem at all. Kinda weird since the front crossbar is still behind the sunroof.
