I bought a Tigerz11 2mtrx2.5mtr it came with L shaped fitting brackets which lets me attach it below the roof rack line, our kayak carriers then fit no problem, racks are Rhino heavy duty, and kayak carriers also from Rhino.
Tigerz11 awnings are built down to a price, we've already bent one of the poles, as has a mate with his, we're going to fit heavier poles, the rest of it is good, just very thin material used for the poles.
I should explain, the poles bent during a severe rain storm over night when the awning filled up with rain, we didn't have enough run off slope but then we weren't expecting rain, the poles that bent were the horizontal ones not the verticals.
