I have an Allu shadow on my truck and have only seen the mounts for the X1. I doubt you could mount the shadow as once deployed all of the weight of the awning ends up in the rear mount. I’ve seen the shadow bend even a less stout roof rack, let alone struts.
I think I’ve seen someone do a foxwing, as the legs help balance it.
That said, I really love how patriot does those pop up struts. I’d like to do those on my Chaser.
