Work vans are the superior work vehicle for the majority of use cases. Lower bed/floor height to make loading easier. Covered rear so your tools/product doesnt get wet or dirty. Able to carry a ton of equipment, taller models you can even stand in and use a workbench in the van. The side of the van is large and flat making it easier to print large letters and numbers to advertise the company. Most modern work vans have better visibility than similarly sized trucks.
