"Our Ezy-Awning is domed so rain rolls off" ~

  This is 99% true, if Ron can make a suggestion to the manufacture.. (grin)

  The rain gutter side fabric needs changed slightly as it will allow pockets of water to form along the mounting bar.  If these grow large enough you will end up with a lovely rainwater shower when you open the slider door (was refreshing ;-)

  Out side of that the thing works pretty darn good so far
