Appreciate all the comments.
The OEM rails use 3 cast mountings each side which are pretty sturdy and the rating is for a dynamic load Gary, I won't be going down the road with people in the tent

Having said that, it's quite possible the tent won't go on the car again anyway, I prefer the convenience of a popup tent for my laning / camping trips where the roof tent gets in the way really or maybe the RV4 Oz tent for the longer trips like France. I shall probably be building a trailer for the roof tent to live on for short family camping trips, opening up to Oz tent height and have the RV4 stood against it for living space and the fox wing on the other side for an awning

Axle should be in the post soon
The OEM rails actually st quite low and even with cross bars on it's about the same height as the rack. I have built in waffle board storage slots on the rack which use up some of the dead space which I lose with the OEM bars.
If I did proper overlanding then I'd have an excuse for a proper roof rack but I don't think I do (have an excuse) other than because I can
Maybe a different style rack is what I need
