Topper awning collecting rain water = annoying

Can't see ANY reason to empty the water before retracting the slide room. It will roll up and the water will run off AS you close the slide room. If you have a deep slide like mine, the awning does not have a large pitch and this makes it nearly impossible to NOT collect water and/or luff in high winds. Very shallow slides don't have as much of this problem. Even ICE will roll right off as the awning rolls up and the slide is retracted.
