I mounted my RTT on the factory roof rack and roof rails. No problem. Quite strong for a factory setup. Yes, there was a document (was a link here in thenissanpath) that verified the 220 lb dynamic weight rating of the roof rack, but I could no longer find it available online. Even if you look at the owner's manual, it says 200 pounds. That is the dynamic weight rating. Dynamic is when you are driving your vehicle and there is motion, and static is when your vehicle is stationary. Stationary rating is typically 3X the dynamic rating. So your RTT plus whoever is sleeping in it should probably be 600 lbs or less. OR, 660lbs or less if you find the other document and want to believe it.
I thought about getting a 'third' roof rack rail for the factory setup to have an extra rail to distribute the weight. I didn't get around to it. After using just the two rails and having zero problems for my wife and I, I decided not to pursue the idea.
