KurtI'm not sure if you've experiences any bending or tweaking out of those "L" brackets? They look a bit on the light side? If you do ARB actually makes some really heavy duty stainless L brackets, 1/4" thick and drilled on the awning side for the spacing between the extruded channels. Makes for a clean sturdy mount that won't bend or deflect in the wind or as you bounce down the road.
I called ARB asking a out the L brackets you mentioned, they said that they did not have any Brackets for Yak or Thule mounts... Do you have a part number? Thanks!
