Fullsize vans don't offer AWD at a reasonable price point.
Either AWD/4wd is necessary when you're going to other people's property because you can't guarantee any given property isn't an icy shithole and when you're a professional being paid by them to be there for a specific purpose the last thing you wanna do is slip out trying to do a 25-point turn on their stupid sloped driveway and put a tire in the landscaping.
Maybe we are talking about different things. AWD is a $4k upgrade on a transit. 4wd buys you nothing and at that point it’s more about the tires.
Even in cold parts of the US your hvac or plumber is going to be using something like a transit. Very few trade jobs opt for a truck. They don’t make economic sense and impossible to secure anything in the bed.
Sure landscaping crews can utilize trucks but even then, your mowing operation can get more value from a transit style van if they are only using pus mowers.
Maybe it’s just in my neck of the woods but if you cannot get up or down a hill because a homeowner does not clear their driveway then it’s a no go. Very acceptable boundary.
What region of the US are you in. I have lived in the south east, Midwest, NY, CA, TX and vans are the norm for most trade jobs outside of landscaping or jobs that can actually benefit from an open bed. HVAC, plumbing, electricians and the like all have equipment that is a lot easier to organize and safely store inside of a van. Now sometimes depending on the type of work that person does they may opt for a high roof and I have seen some opt for the chassis cab and go with a third party body that gives even more room but still enclosed and may even choose the van chassis.
I am quite surprised to hear you have never seen an electrician use a van. That said there are certainly specialities where it’s more common.
90% of trade work is all on pavement and trucks suck for tools. If you are a logger yeah sure you may be using a truck to get to your equipment, similarly for lineman but for the vast majority of trade jobs companies opt for commercial vans. You are describing trade work like it’s the tv show landman.
They absolutely are for consumers but not so much in business. Vans are superior for most trade jobs within the US and pretty big sellers. Yes there are some gaps like if you in parts of Alaska or other very rural parts of America but largely trade jobs are spending all of their time on pavement.
