I'm working on repairing a truck-trike, that was gifted to me when a friend was clearing out "junk". In it's original form it's designed to carry up to 500 pounds. We'll see how that all works out this Summer. ;-)
Panniers, a frame bag, and a back pack work for most things. And a trailer for when I need a bit more carrying capacity. That's been my approach for over a decade.
John Jeavons book, How to Grow More Vegetables (than you ever thought possible on less land with less water than you can imagine) is a wonderful reference on the biointensive method (https://johnjeavons.org/books-and-videos/). And it's now in it's 9th edition.
