I was wondering if anybody on here has mounted the SmittyBilt Overlander XL on the LC using Yakima or Thule Cross Bars. I know the factory cross bars are too weak. Just wondering how wide to put the bars and if two bars will be sufficient or if I should add a third bar in the middle. The tent is 47" x 76" The max width allowed on the factory rack is about 50", which would mean about 13"overhang on each end.
