WOW, when I talked to my Carefree factory Rep. he insisted that the knobs be loose on the electric awnings unless you want to "tip" one side for water drainage.
BTW Dometic says the same thing.
Every brand new (or used for that matter) unit I deliver has a sticking awning. It is the way the arms fold together. They fit very tight. Unless you are perfectly level, they will likely stick. Even at perfection, they still sometimes stick.
