I built very light .020" aluminum side panels for my -4, particularly to cover all the control cables, wiring and mechanical exposures to mitigate any fouling by passengers and loose objects.Also, armrests where a requirement. My wife has requested simple storage for the back, and I plan to add some elastic netted or leather pockets for sunglasses, ect. I have a simple centered "glovebox" for my phone and sunglasses in a center panel. I kept the design very simple and snag proof, as I don't like cluttered interiors.
