In Europe we just call these vans, as 99% of the time what's meant is a panel van. They have a roof, so you can even carry stuff when it's raining!

American-style pickup trucks are hardly ever seen. If you have stuff (like construction equipment, bulky materials) to move that can get wet, and wouldn't easily fit in a van, you use a dropside van as it's much easier to load and unload. It's the same cab and chassis with a different rear end.
