Im too slow in the head to remember to press up on the awning as I frequently enter and exit. A sad commentary on my poor memory or abilities, but a fact pretty much non-the-less.
My 4 year old son certainly will have a hard time complying with my request to reach up and make an effort to ensure no contact between the door and the awning. He still struggles at this point with "open ended questions", but I am told at this age, that is still more or less "age appropriate". My 2 year old daughter cannot open and close the door yet, but more years to wonder how she will do avoiding door/awning contact. My wife? Well, she has the best genetics to remember something like that, but it seems after having children, she developed what she calls "mommy brain"...she forgets things constantly since having children.
I also will camp and have guests with me with some regularity...my nephews locally camp some weekends with me....most small kids less than age 6. My nieces and my sister are going to join us for a week on Tybee Island June 2015 and being they also share my DNA at least in part, I cannot guarantee they will comply.
"Rollers? How then do you close the door, or is it attached to the outside with sheet metal screws and looks like something to hang a bird feeder?"
yes, and you bring up a good point...if we made it even bigger, then we could hang a bird feeder from the larger roller fixture...bird photography is a budding hobby of mine.
Also I have a link to my first attempts at hummingbird photography...photo taken with a tamron 180mm macro lens shot with nikon SB flash mounted on camera

Other options I thought of included taking an acetylcholinesterase inhibitor..would not fix the problem I have entirely, but would slow the progression of memory impairment some or if I am lucky totally.
Also could consider capital punishment for offenders...not sure the wife would buy into that though...DHR would frown upon it...
My policy in my camping in the past nearly 1 year has been to try and remember and be careful entering and exiting...but sadly those efforts have proven a failure as I frequently find myself opening the door when its raining, the door contacts the awning...then I say "oh S%$T, I dun forot!"...my then 3 year old just goes in and out without a regard for the contact...
