Just wanted to offer some advice to anyone mounting something to this rack that spans the entire length.
For reference, I have the full Victory 4x4 rack and mounted the ARB2500 (8.2ft) awning. This awning weighs 30ish pounds and is over a foot longer than the rack, so I chose my two mounting points to be the rear-most crossbar and the front-most crossbar. Everything installed perfectly! Then it was time to hit the trails where I instantly realized my mistake. Due to the front mounts of the rack NOT being bolted to the roof, on every bump I drove over, the front of the rack shimmied left and right, effectively rubbing the roof and making loud squeaking noises. This is due to there being lateral flex from the middle mounting point of the roof to where the rubber feet and fairing touch the car. So whenever I hit a bump, the heavy awning would shimmy and bring the front of the rack with it (again since I mounted the front of the awning to the front-most crossbar).
So here’s my advice. If you’re mounting something long like an awning, move the front mounting point closer to the middle crossbar (where the rack is bolted to the roof). I adjusted mine yesterday after the trails and so far it’s removed the rack shimmy, but I’ll know more once I get back off-road. Additionally, I’ll be bolting down flat metal bars (available at Home Depot) in an X shape on top of the rack to create triangular stability between the rear and front of the rack. This should make the entire thing solid, as in you wouldn’t be able to replicate the shimmy by hand like you can now.
On a side note, I used Victory’s awning mounts and they are pretty awesome. It’s such a clean install and they mount really well to the crossbars. Highly recommended.
