Roof rails/bars for 2011 navara

[AdamNavara2011]

Evening guys! New here so please let me know if this is the wrong thread.

Iv been looking at roof bars/racks for my tent box to sit on. As of yet I haven't found any that can hold 200kg (the weight of the tent plus 2 adults) does anyone have any experience eith mounting a tent on thier navara? If so how dod you do it?

I have the pre installed bars on the roof so I'm trying to figure out the best bars or way of mounting a tent box! Any help is much appreciated

I've got Pro-Rack Whisper Bars on mine. 95Kg dynamic loading, but they're supposed to hold 300Kg static.
