Awning track on new Bailey Caravan

Can anyone give me the answer to how one gets a full size awning around the almost right angel corner to the rear of are Bailey Caravan with the alu-tec body shell. It  and took two of us,one to pull one and the other push the other end from the front of the van, it was just as difficult to take the awning down, its easy to remove once its around the corner just like any other awning slides right out, but this corner is really something else, as anybody else encountered this problem? just can't get the awning cord around this right angel bend!
