I lived in (and now commute through) a neighborhood of older houses, and higher incomes, so I see a lot of contractor vehicles. It seems like it breaks down as landscapers and lawn services use the pickup trucks; trades companies (plumbers, electricians, HVAC, carpenters, painters, etc.) use vans or box trucks; and the independent guys tend to use Dodge Caravans. Nearby, the university uses fleets of kei trucks (the low-speed versions because "freedom"), Ford Model E vans, and Caravans. I think the landscaping crew has pickups.
There are an increasing number of company pickup trucks, but most of them appear to be pavement princesses, used only for their usual function: transporting egos, not equipment.
It's also residential. On big commercial and industrial construction sites it's almost all big but fully functional trucks for exactly the reason you mention; they have to be able to haul trailers and heavy equipment --like generators, water buffalos, sand-blasters and the like-- over unpaved rubble or dirt.
But those are almost all company vehicles in any case.
Ours are utes. Either road versions or 4×4 versions. American trucks sell here but they're seen as a joke in both capability and practicality, so it's assumed the owner is very insecure about something or not very intelligent. As a result, they're very rare.
Until you have an odd size item like a door in frame. Or need to move something like a 1 man post lift. And since you know you won't be cleaning it out as often so your always going to have extra crap your hauling for no reason. I'm just going off every pro that has shown up for work at my job sites in a van.
I had a 1 ton Ford van for 12 years and I could haul a pallet of flooring or 20 sheets of drywall inside it, as well as lumber 12 feet or shorter. Anything more bulky than what fits inside a van like that would have difficulty fitting inside a 6.5 foot truck bed without a rats nest of ratchet straps and hanging way over the tailgate.
You have the right of it. If it won't fit in the van, you hook up a trailer. The cost of the van and trailer combined is still a sight less than these living rooms on wheels.
Aren't the vans we're discussing here just as big (or even bigger if you consider the height) as the truck? It's a truck frame with a big enclosed box on top
Yes, but full-size vans aren't a popular vehicle outside of passenger and tradesmen applications, unlike pickup trucks. I was only pointing out that North Americans apparently prefer to have a passenger vehicle where 40-50% of the wheelbase is unused useless space.
