Just thought OP might look into it with some input from someone that actually has and uses one.
My sunshade is 2 pcs, 8' x 6' ea and neither of my A&E/Dometic awning motors would lift even one section even with the 2 or 3 extra turns on my torsion spring. I've seen others roll your type, but one section of mine should equate to a 16' x 3' which is smaller than yours. Must be a big difference in material weight. of the shades themselves.
