I have the Black Widow side and rear awning. I have had a ironman rear awning but it was not the best, Found a black widow rear awning in Darwin and had it shipped to me. As I already had the side awning.
Yes you will say they are very pricey but you get what you pay for in my opinion.
The canvas provides heaps of shade and does not let light through so it works for me.
I just did not like the arb,foxing and ironman because I found the canvas to be very light in the canvas for me.
Each to your own and buy what you can afford and be happy with your purchase.
