Yakima has the best system that I have found. Expect to spend a few pennies but they appear to be worth it. I plan on getting one soon myself, sometime you want to haul a little wood and a rack is the best place.
IF I could find a stock roof rack, I would most def. add that to my SRT. Read up a LOT on how others have mounted it and feel confident, with a few measurements, some bolts and fender washers, that I could add it to my SRT. But I have yet to find the parts.
