The retractable car awning attaches to any standard or after market car roof rack- on universal/adjustable mounting pedestals. The height of each pedestal is adjustable to clear large lift doors found on most SUVís and minivans. For vehicles that do not come standard with cross bars on the factory roof rails the retractable car awning system can be deployed to the side of the vehicle. It deploys by one person, and is completely set up in less than two minutes. No support legs or guy wires are required. When you are ready to get back on the road, it can remain ontop of your vehicle, in its travel bag.
