Please excuse the lengthy post, this forum has provided me with so much information that I'm being overly informative in an attempt to give back to the community. I'm running an ARB2000, mounted to a Rola roof rack (attached to the factory rails) using cheap light bar mounts, and illuminated with an LED strip (that I pieced together, powered by the 12v socket in the rear cargo area) on the underside when deployed. I decided on the ARB over a few lower priced alternatives due to their reported customer service, although I have had no need to contact them. I have deployed this awning at least 25 times in the past 6 month, by myself, and I have no complaints. I'm glad i chose the 2000mm length as I personally feel that it "fits" the 4runner lengthwise without interfering with any of my doors, and it provides sufficient usable shade for me to throw down a mexican blanket and allow my family of 4 to escape the hot Texas sun and rain when necessary. I had a pair of Vans BMX grips laying around, so i cut a piece of grip and wrapped it around the Rola rack lower tubing to act as an "insulator" in an attempt to prevent metal on metal contact/wear between the mount and the lower rack tubing. I have provided links below for everything that I used. It is worth noting that I mounted this awning to my Rola rack using cheap light bar mounts (I had to drill one new hole in the mounts to match the awning channels) as a temporary solution to get me through a camping trip. I decided on light bar mounts after finding the Rola tubing dimensions here.
https://www.etrailer.com/question-17958.html As of yet the mounts haven't budged (installed April 1st, 2018) and I haven't upgraded my mount setup, even though I have more mounts sitting on the work bench. As of the time of writing, I have zero complaints about any of these purchases. All hardware has remained in place, but I did add a small bit of blue loctite to the mounting hardware.
