In addition to the payload. Payload goes in the back! Fill it with stones then put five men in it to shovel the stones. You'd need two vans for the same purpose. And if it's roughly the same size, what's the problem? Vans like that can be nice too, we see lots of Ford transits here in the states for tradesmen. Similar use case to what you're describing.

Towing capacity, payload weight, carrying 3 more people, bed width, drivetrain? I think many trucks are way too big, and it's silly to own a big work truck if you just use it to go to the grocery store but it's really about so much more than bed size.
