I have the same problem, and did a lot of research and looking for solutions. The first one that I found actually worked pretty good for the rain. It is buried deep in this link: http://www.outbackers.com/forums/ind...l=awning&st=75
The guy actually has some video of him doing the work....nice job. So, I added a center support. It really helps out. Soon after I did that, I stumbled across a post somewhere that they now have a fix/mod for the awning to allow for the tilt. You will need to contact the dealer where you got the camper from and have them order a "Kit" for getting the
tilt: 3312508.017b. (Carefree is my awning type). They will need to have your model and serial number also.
I haven't had the opportunity to install it, but did go out and look it over with the awning out -- looks like a pretty good fix.
As for the wind and deflapping...haven't solved that one yet, but I have tied it down and been relatively happy.
