Thinking of Adding a Roof Rack

...but first I was wondering if anyone had any pictures...

I was thinking of adding a roof rack to save space in the bed. Use it to carry my jerry cans, jack, shovel, ax, small toolbox, and maybe even a spare tire. The only thing I'm not really into is how high the rack sits on top, expecially when using the Yakima mounts (also how those mounts stick out on the side). The stock roof rack mount you can buy isn't bad as far as height but I was wondering if anyone has resorted to anything else to make it appear that the roof rack itself is resting on the cab (though it obviously is not).

What I'm not too into...
