We prefer the easy life so sides are always removed when erecting any awning.
My technique also, though I suspect with the light weight fabrics I might do otherwise.
My choice is to simply reduce the weight that inevitably drags on feeding the bead through the rail, as stated I do it single handed and without the use of a step ladder. Carrying the latter to me would simply add to the clutter.
Also, in refolding things to bag them up I find it being in multi pieces makes it easier for me and IMO poses less crease risk on the vulnerable "windows". I have no option but handle the Magnums tall extension as a one-piece task, and that endorses my keeping the main awning task to the way I do.
The people watching thing, even the helping, plus realising the weight on threading them makes me quite sure I will leave having an air awning to them.
I am all for the easier life!
