HobbyTalk is right............I have the flat pitch model even though my awning does not go over the door (it is a bus and the door is all the way up front)......I like having the awning high and out of the way......Even when extended the awning roller tube is still 7 feet high.......I do not have to worry about walking into the arms any more......The kit I got is the cheapest that Carefree makes and
