As was indicated before- there is no commercial product such as these. Simply tying down a power awning isn't sufficient as the arms need support help themselves. They're just not strong enough to take a whole lot of wind.
OldCoot first made up a set of "Power Awning Tie Down Poles", but stopped making them a short time ago. A few of us were lucky enough to buy a set of his originals. From there, ]f1100Turbo
started making a kit with Old Coot's design as the basis with a handful of changes to the design. If you send him a PM (I've linked to his profile- go there and you can choose to send him a PM), I'm sure he'll hook you up with a set.
Most people install the poles so that they're always mounted to the camper. With my OldCoot poles, I installed the mounting bracket to the pole and simply mount the poles when I want them out. I'd really like to find a place to paint them up (I look like a "slow" monkey with 2 left hands when I try to paint things!) before I permanently mount them.
