quick answer !
I know, but it would be nice to hear the experiences from some people that had it fitted and used for some time...Thinking about fitting the rails and directly on top of that a tray of some kind. (so without the use of cross-bars) Want to keep the tray nice and close to the roof, less wind noise and less option for it to move around.
How does it work out for you, did you already do some substantial k's on dirt roads?
