At SEMA 2010 I saw the FoxWing Awning sold by Rhino Rack USA, This amazing awning mounts to the side of your roof rack, basket or platform and provides a fold out awning amounting to a three quart pie shape around one side and the back of your vehicle, you can order it for the driver side or passenger side installation (I chose driver side).

Made from the same high quality material (rip-stop poly-cotton canvas) used by OZTENT the Foxwing Awning is UV protected, water proof and mold resistant. The solid frame consists of anodized aluminum and corrosion resistant hardware so it wont rust. All telescopic poles, guy ropes and pegs are included and come with their own travel bag for neat and tidy storage when not in use. Perfect for the avid camper, traveler or tradesman, the Foxwing Awning is the quick and easy solution to protect you from the elements.
The kit also has an optional sand bag kit to help hold down the awning in high wind situations (I purchased one of these as well):
And optional extensions that zip in to any of the five sections to provide side walls, with four extension you could build a large tent (I purchased two extensions):
