This is how I deflate my air awning (4 beam, single inflation point Vango Agora):
I zip up all the windows and doors.
I take out all the awning ground pegs except the farthest rearward corner, leaving the footprint pegs in place.
I then deflate the awning, purely by valve so that it collapses, but leave it attached to the vans Multirail.
I then pull it back off the Multirail and then drag it forward again, square it up so it’s all within the footprint including the tunnel.
At this point, I might temporarily use pegs to keep it in place depending upon wind.
I then use the pump to deflate as much as I can, before closing the valve.
Now I selectively remove the last of the pegs as required to enable my folding:
I fold one side into the centre and then the other side into the centre, before folding the side again into a full length quarter.
I then fold the length forward, slightly less than half way.
Starting at the fold, I then roll it up forwards as tight as I can. It tends to slip forward slightly, which is why I fold slightly less than half way.
Then I tie it off with two ties, put it in its oversize bag, ensuring I’ve got it into the bottom of the bag properly. This bit matters.
Then finally I use the bag straps, bit by bit, to further compress the whole thing before zipping the bag.
No drama and no rolling about all over it.
