Back in November PeterVS started a thread showing his improved awning support arms, (as installed on our bus). I posted the following re that experience. Jeff's warning should be taken seriously.
BrianEThe results of getting ahead of yourself can have unpleasant results. Even though both awning lock arms were engaged, somewhere in the process one of them got bumped open and the other one was tripped when the awning came loose in my hand. Suggest that the patio awning should be taken down with two guys on ladders at both ends. Much less expensive.
