While driving across New Mexico, I had the driver side 22" awning unroll. The front end arm moved away from the trailer body but the rear arm did not. This caused the awning roll to bend.
The road side repair was to tie ropes to each end of the awning roll, throw the other ends over the trailer and tie them off on the curb side.
At home, I extended the awning all the way out and tied the ropes off to the tow vehicle. I then formed (bent) the awning roll straight. The awning is now usable without replacing the roll at considerable expense.
Lesson to learn: Carry a couple ropes and use a plastic cable tie to secure the awning latching device.
