One of the most highly upvoted Reddit posts on /r/fuckcars mocks large pickups compared to the utility of a kei truck. https://reddit.com/r/fuckcars/comments/sdrgv3/japanese_truck... A kei truck has about 90% the bed length of a pickup while being a lot more nimble. The lower bed is more ergonomic to load and unload too.
I can fit a bed, 3 months of luggage and a bicycle in mine. In a pinch, it's a brilliant microcamper. It's a big box on wheels. You can do what you want with it.
It's not a nice car, but it was designed to serve real user needs. That's why they're everywhere from Morocco to Poland.
