I think I unpinned my legs and ran them vertical exactly once and pretty much hated it. I did not find the awning is stable with the legs vertical as it is when they're kind of triangular and latched to the body. But I have the 21 classic with a curved legs and so they're kind of weird when they're on the ground straight. You definitely have to stay come down when you do that. Otherwise the awning will lift off and the slightest breeze
