Do you have an electric awning? Here's an oddball thought---.
It is possible to roll up the awning fabric the wrong way. That is, if your awning is out and you hold the out button, the roller will roll up the awning fabric, the wrong way. It would make a nifty water collector if that is how it's stored.
Don't ask me how I know, because if you do I will lie.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
