Very nice idea on the scissor lit!
If the legs were paired two inside and two outside, cross bracing could be added between the inner legs to support the load crossmember and also help prevent racking of the frame while still allowing folding. The two outside legs could be toward the Gladiator for a little (3") extra clearance. Cross bracing on the top longer edge of the outer legs would also still allow folding flush, like folding chairs.
I love checking this thread for updates. It seems there are constantly great ideas and inspirations popping up.
Well done.
