the OD is 1.25”Beautiful rig. What did you use to mount the awning to the LoD rack? Do you know the diameter or the tubing?
Getting that batwing on was a pain. No mount I could find fits the diameter of the tubing. I wound up using the arb tube mount for its curve around the bar, and then used large washers to hold the bolts in place to the holes already in the rack grates. The tent also adds extra support holding the mount down to the rack. (See picture). It is very sturdy, but without the help of the pressure of the tent, I don’t know if it would work. The ARB tube u bracket is too small to fit around the diameter of the cross bars
