Yeah it's also that American pick-ups usually don't feature 4WD (unless as an even more expensive option) which is kinda a need if you're into farming. It's a weird niche for people that want to show they are outdoorsy somehow but aren't really.
And for people that just need to move a lot, having it exposed to the open air is usually a dealbreaker. Panelvans are much more popular for that. Or MPVs with removable seats.
I have seen other countries where they are popular though. Like in Australia where they call it a "Ute". But yes also a long-distance country like you say.
