I went to a canvas place in Mordiallic, and he made an awning to my specs for less than an ARB one.
Mine comes out off the back of the car 2.4mtrs, then drops down to the ground with eyelets at the bottom for pegs, and if I remember ties to hold it to the 2 poles to stop flapping.
not spring loaded, so you wind up manually, but for the price, its functional.... Shame I hate the roof rack.
