IMHO, having a door with the hinges forward instead of the typical 'suicide door' hinged to the rear is not a bad idea.
The 'suicide door' has been known to occasionally pop open during travel and damage both door and AS skin.
Some have added a door wedge to guarantee the door will stay shut during travel. It fits and locks into the grab handle and extends enough to physically block the door from accidental opening.
On my 22 footer, the open door prevents opening the forward dinette window at all, as the door is guaranteed to break the dinette window glass when both are opened...and there is plenty of room to hinge the door the other way.
I'd go with an awning sized as shown in the #2 thread entry example, and add something to the forward awning arm to hold the door open safely when it is open...getting hit with a wind-blown AS door assembly is not fun--don't ask me why I know this all too well.
Also note that if possible, having awnings on all three sides helps keep the AS a lot cooler when out in direct sun.
Sometimes we only need the streetside smaller awning to keep cool, and don't bother with opening the big curbside one. Its very quick to open and close.
The rear awning over our escape window is nice to have, but mainly shades the window, not the AS body like the streetside one.
On a smallish trailer, I'd avoid the complications of a power-operated main awning. They seem to be a PITA.
