But on the Magnum, it is the roof, not the side wall that needs the direct pull?High Buckman. You dont need the eyelet, you can attach to the adjustable buckle that normally gets pegged right at the rear or one of the pegging points. You could also make an unobtrusive eyelet in the mud wall.
I push our Magnum up the rail whilst somewhat undignified, draping the roof on top of myself so the bulk of its weight is not taken by the rail.
In my experience it is avoiding the awning's weight hanging from the rail, but otherwise supported, that is the essence of easing threading the bead.
There is no reason you could not combine doing that with using the Kampa Dometic Easy awning pully, and though I started collecting bits to make a DIY version, I dropped doing so having never previously needed one. I was planning to sew a "D" loop via a tape, under the roof "wing" extension.
As I age, maybe I should resurrect the project for the minimum effort involved.
