I'm not familiar with the USA. What do contractors over there do in terms of clean/dirty clothes? Do they change into clean boots and trousers before getting into the truck? Or are they all in roles where they don't get their hands dirty?

In my country, vehicles marketed to tradesmen and agricultural workers usually aim for a hard-wearing, easy-to-clean interior that's fairly spartan.

Using my wife's fairly recent (2024 model year) pickup truck as an example, every horizontal surface is covered in papers, clipboards, horse tack and medications (she trains horses and operates a horse rescue). The floors and kick panels are probably muddy at this time of year, but I'm so used to it that I don't notice. The surfaces that aren't covered by papers or something else have a nice thick layer of dust (the truck spends a lot of time on gravel roads).

It might actually be vacuumed out a few times a year, but that's far from a priority. Generally, the cleanup only happens if one of us has to wear "nice" clothes to go somewhere.

But bear in mind that the areas that your body touches tend to clean themselves simply because you're moving around. So, the floors, dashboard, etc., might be muddy or dusty but the seats will generally be clean.

The basic "spartan" trucks tend to be for uses where you don't have to travel very far. If you're driving a hundred miles or so on an average day, you'll want to be as comfortable as possible or it gets old really fast.

Because the only truck owners the people who bash trucks see are their neighbor across the street who is that guy.

The demographically comparable guy who commutes in 80mi one way from his "country estate" in his Audi isn't on the internet bashing truck owners because the guy he lives across from uses his truck.
