re: Why can't we get a compact, 4 cylinder diesel pickup here in the US?

I lived in Costa Rica for a few years and had a 3L turbo diesel Toyota Hilux Crew Cab 4x4. Slightly bigger than Tacoma but smaller than a Tundra.

I've had 6 different trucks over the years.

The Hilux is hands down is the best truck I've ever owned.

I think they'd sell like hotcakes here in US. I looked hard into importing in back to Louisiana but no dice.

They make more money selling larger trucks. I don't believe they want to eat into their profits.
