RPM007 - I've confirmed that the stock KK roof rails will fit just fine on a KK w/ a SkySlider. Everything lines up and connects correctly. Obviously you won't get the clearance you need if you put on the stock crossbars and open up the roof, but for my needs why would I want to open my roof when there's something on it anyways? The crossbars are easy enough to put on and take off. So my plan is just to keep them off when I'm not carrying stuff up there.
