Love the ingenuity!
Personally I wouldn’t go for it. I’m a big shore fisherman. Typically going through brush, trees, etc the rods need to be manipulated through and having them tied to a small box that wouldn’t even hold all my tackle anyways, just wouldn’t work out.
Perhaps for just catfishing nights, but then the box is way more than I need for that.
Its a great idea though, good luck!
