Dave,
The reason your main awning does not go closer to the living room slide and cover the door is, the entry handle on the coach. It is to the left of the awning arm. If you put the awning arm on the left side of the entry handle, it would not allow the living room slide to close all the way. As many have said, there are trade offs when it comes to rv living.
