I disagree with others (as usual) Awnings CAN take wind.....if the wind isn't coming from a direction that causes it to blow away. :) :)
As for your awning, OPer.....3 hours since you were told it would not be bothered by rain, and it was only drizzling.......it collapses. I'd have hooked that baby up and taken it back to the dealer right then. yes, something was wrong......something mechanical. I can't see that YOU did anything wrong.... An electric awning...you just push a button. NOT your mistake!!!!!
As for the one that says they'd never have an awning. :) Our friends lost their awning last summer. Thought they'd come to AZ....Yuma. The park put them in a space where the patio/front door is on the south side. Yeah, you can bet they'll have an awning come next winter. :)
