Vans are commonly used in urban areas, especially by businesses, but suburbs, rural, and construction benefit from higher clearences of SUVs and trucks.
SUVs are also usually much better in hazardous driving conditions because of a more optimal weight distribution.
Reality is, people buy these things thinking they would drive them off road, and never actually do it.
It's possible to make an off-road van, by the way. It's just that real demand is so vanishingly small that you don't really see them.
I deal and have dealt with enough deep snow that would eat a van.
I still might get a Sienna Hybrid for daily commuter
It also makes more sense for me to get a large SUV, as towing is important.
The SUV or Truck is still more capable in hazardous road/off-road conditions compared to the van.
Though in my current neck of the woods, a Sprinter would satisfy my needs well.
I had a RWD pickup with snow tires and went anywhere I wanted to through two utah winters and many vermont ones too.
