The awning is actually not that hard to work on..Armed with a few simple tools and, a drill and a pop rivet gun is about all you need to work on it.
The biggest challenge is the "charging" of the awning's spring after you've completed the work.
It's rather surprising but, the internal works are the same for all sizes except for the number of turns you use to charge the spring.
Just be careful in doing this one aspect of the operation because, if it gets away from you...you could get hurt...
