Thanks for the insights all! I think if the Thule ones don't measure up, I'll go with the Yakima carriers. Reason for going with front wheel on carrier is largely due to the fact that when we camp the cargo area of the Yukon is packed with our clean clothes and consumables. DW isn't big on tossing dirty wheels in back... I don't, however, like the idea of constantly needing to adjust them. DW also doesn't like messing with the wheel... Hmmmm....

I could make your eyeballs spin with a discussion of aerodynamics and drag, induced eddies and turbulence!
However, makes no difference whatsoever with our setup as we're rolling 12'-3" road to top of A/C. So there's already significant frontal area, though profiled, lending resistance, and it would be only a minor variation over hauling our two kayaks on their J-racks. With the 8.1L, it 10.3 mpg average no matter what.
