• the larger one does do more:

    • Pick up 3 extra people
    • Can roll down the back window to let long planks of wood through

    These are the only extra advantages I can see, and they are seldom use cases at best.

    Fine, if you’re a contractor driving your workers to/from work whilst carrying all the equipment, on a daily basis, such a truck is very useful.

    But how many people who drive these do that?
