Roof Rack installation

Ive been thinking about doing a off road roof rack on my 04 yukon. How hard is it to install these? If you've done it can I get some pictures if possible?

I'm thinking about doing something like this.

I have a yakima megawarrior with one extension, two bike trays, and kayak pads. The oem cross bars on the yukon were a little to flexible so i replaced them with unistrut clamped onto the rails.
