This crazy world has got me thinking about repurposing one of my recumbent tikes into something a little more practical, which seem popular in continental europe, like https://www.wintherbikes.com/product-items/cargoo/
Brad has a few cargo bike/trike plans already though not that type. I know what you mean though in that I too am thinking more along the lines of what's practical rather than what I've built to date which have been primarily built as toys.
