They still make single row ones. We have many at my workplace. Usually tradies that work for larger businesses or local governments use them. Smaller trade businesses generally the dual/super cab ones. They do have their uses but most people don't use them for that purpose.

Ranger XL single cab or Hilux single cab still around. The Holden Colorado was my favourite as someone that did a lot of long drives but that doesn't exist anymore.

At the end of the day, most people want to drive a bigger car because they feel safer when though the bigger vehicles are the problem.
