Isn't possible to just move it over? From your picture, I can't tell how it's attached but....
If it were mine, I would maximize
the width so it went over the door for the maximum shade opportunity.
My bigger concern is the effect of a strong wind coming up suddenly. The main complaint I've heard about these is that it is somewhat difficult to slide the "top" into the track unless you carry a small step ladder. Now for us with little trailers, that kinda seems like a waste of valuable space to me. I guess if you travel with the awning in place, rolled up, that would work, but I would think that may put undue stress on the fabric at the track.
BTW there are no additional holes required for these type of awnings...
Were you in a "covered wagon"?? I see that you've got INDIANS~!!!
I know Denver has a reputation of still being a cow-town in the wild west, but I didn't take the picture...it's from the RL website.
