As a tradesman for over a decade, I much prefer working out of a van. They are a bit more effecient on average. They haul stuff really well and larger ones can even be used as a small workshop/well organized storage. Their decks are lower and easier to load and they accomadate large cargo without the need for tarps to water proof. Strapping stuff down is easy too as the walls can help. Many vans these days can be bought from the dealer ready to tow. For bigger jobs cube vans/trucks are also an excellent option.
