mine is a dedicated overlander/toy so the bed is just full of boxes (the empty space perfectly fits a tote). shafts went under the bed hung up like conduit. not sure why I ever dragged shafts around with me. my wheeling style is very much on the cautious side (especially when it's my ride home).
I love geometry! but unfortunately the last class I had was a couple decades ago and my brain now sucks and doesn't remember most of it. being a 3 dimensional system that moves in several different arcs and rotations is why I love computers.
