just bought a '10 with Vista roof. 
so far no luck finding a ski rack for the roof- because of the way it all opens - out and UP. 
option? 
rear lift gate rack.....or? 
higher profile rack? any out there? 
traded in the Suburban. It held 6 to 8 pairs on top, no problem. 
of course it only got 11 MPG, at best. But drove thru anything. 
Ski season comes up soon, any help is appreciated.
