To help offset that rubbing door issue, RAISE the awning leg (slightly) that is on the open side of your door (open door, raise leg and swing door ...trial and error!) THEN lower the awning leg on the opposite side of the awning to the desired angle.
NOW ....here's a l'il bonus
Reace talked me into buying that I thought (at the time) was a waste but we find we use it every time we open up the awning. There is available an OPTIONAL center support rod (adjustable) which one places into the outter edge rail and rests on the inside of the bag awning on the roof. This is added from underneath. What this extra support does is to give the fabric more support where it needs it must in the rain. It helps ease the stress on the fabric and also helps a l'il bit to direct the flow of water to the sides on the open awning. (....also gives you an extra 'towel drying rack', looks ugly with clutter on it, but it works!!)
A word of caution here people, Rease had fiberglassed a small block of plywood to the body side (from the inside) where the awning support bracket would attach to the body. These blocks were added to give the attachment screws (for the support brackets) something more to bite into. IF you were doing this add on project yourself, it would pay you to do something similar to avoid screws backing out of the fiberglass body. We find that we almost NEVER use these brackets as their use invites ME to be walking into them on a regular basis. We choose instead to use the awning legs in the vertical position. Yes, you still need to walk around them but for some reason does not see so obtrusive.
