The biggest upside to a truck is that the bed is outside. It's perfect for wet, stinky, unsanitary, powdery/sandy, etc can cause huge headaches in a van or hatchback, and doesn't require you to pull a trailer which can be a real pain in the ass sometimes. It's like the multitool of vehicles: bulky, not the best for any given job, but capable of doing almost anything.

Yes there are a lot of people who get them for stuff that can be grabbed with a car more or less. 6 bags of concrete and some 2x4s can easily be gotten in a car infrequently.

And yes I likely could make a car/trailer work, but some sites are off-roading more or less. So even if you’re a lackey, sometimes the site just requires more than a car and other options than a truck aren’t as practicable or convenient.

Yeah every could go and a rent truck 3 times a week. But that’s just silly after a point, and yeah sure there is sometimes you don’t need it for 2 months as well. That’s reality.
