I have mine mounted on the Driver's side. Back when I had my XTerra, I did it this way because I felt safer driving with my Hi Lift Jack mounted on the passenger side of my Gobi roof rack. So, I got use to the idea of accessing stuff I regularly need from the interior when I have the awning out from the driver's side. Conversely, I packed the rest of my roof rack to have things I regularly needed accessible from the passenger side. When I switched to my JKU, my Hi-lift moved to the interior , but I was already accustomed to a driver's side awning and have stuck with it.
