I suspect I would have a problem with a permanent mounted deployed window awning when in travel mode. I know I would be snagging something on the passenger side with the overhang... I think I would want one that can be rolled out when you setup at the camp sites... Much like you main awning operates but on a smaller scale.
While you are thinking about window awnings - maybe a solar panel on a hinge over the windows might be a good idea for you. They should make great window awnings and you can get some solar power to keep your batteries charged as well...
These would be mounted on a hinge pin and closed down and locked in place when in travel mode.
Just a thought from reading what some others are doing.
