With any mobility or reach challenges the concept of threading the awning complete with its frame through an awning rail seems, from a weight handling point of view alone, a flawed idea.
One that even gets more so if the product has any quality about it, so the fabric and bladders have more weight to them.
The whole" air framed" concept, apart from it less likely to damage the van if it gets blown about, fails to convince me of its merits on any design point, least threading it up.
We use a Magum that I, happily, at even just shy of eighty cope with single handed and without a step ladder, or we use a Shadow canopy and windbreak.
I have assisted others, and extensively witnessed others with air awnings, porches, part and full, enough to leave them well alone, at least I will until the design concept is sorted. That's not to say some can't make even putting up a poled awning into a challenge, it does not need to be, though most don't try lugging the frame with it through the awning rail!
