A Fiamma Magic Rafter prevents noise totally. With that and decent storm straps over the tension bars it can stay out in normal weather conditions. I use mine (4.5M) all the time. It has been out for two weeks so far. The odd puff of wind has no effect.I really like the -idea- of an wind-out awning. When the sun is beating down, or it's drizzling, it provides great protection. Provided there's almost zero wind. And it is pretty convenient to wind it in and out without needing storage inside the van. But even in the slightest wind, they flap about and make horrible noises inside the van. Even with tie-downs, I don't trust it enough to leave it out when we go out. And I've got up at 2am too many times because the flapping is keeping me awake. It's just a constant faff.
