What are the factory rails rated at? (weight wise)
I believe the OP is looking for the cross bars to go onto the factory rails. I'm personally using the Thule Rapid Crossroad 450R to hold my RTT.
Do you just run 2 crossbars on your Thule Rapid Crossroad or did you buy a second 450R for a total of 4 crossbars for your RTT? Are 2 crossbars enough for a Tepui Autana 3 or will we need 4 crossbars?
