What is up with those pickup trucks anyway? Why do so many people in the U.S. (and elsewhere) buy them?
Everything that you put in the back is subjected to weather and one of first additions people buy is a cover.
Compare that to a mini bus or transporter, you can transport as much or more than with a pickup truck, protected from weather, and you can add or remove chairs, if you need to transport people.
If you have a transporter, you can also much easier furnish the inside with racks etc, to improve space use.
