Everyone in the trade business uses vans. For heavy duty hauling they obviously use something bigger than a fucking pickup truck.
My 2015 Dodge Ram Hemi pickup truck and 24,000lbs/11,000kg tandem axle tilt bed trailer would like a word. Pretty hard to get a skidsteer or tractor in a van…And the cost to own and insure even a single axle truck and trailer is far more expensive, (I’ve done the math), and far less versatile. And hiring a large truck makes scheduling very difficult for weather sensitive jobs far too often. Not to mention the loading and offloading almost always needs a ramp or dock of some kind for those larger trucks - hence the tilt bed trailer.
And when not being used as a haul/work vehicle, it can get groceries or even a 6 pack of beer…
That said, do urbane Cowboys/Cowgirls need a pickup truck? Probably not. But it’s a free, but often stupid choice they are free to make.
