I can't speak from the perspective of a truck driver, but I drove CAT vehicles in the military in-country. We lived in them as well. The reason the boots part is important is because if you're living in a vehicle the dirty parts house a lot of nasty stuff that will get you sick. To offset that, you pull everything out of the truck and clean it. If you have to keep doing this then it adds stressful and exhausting repetitious work to your work life. If you ignore it you get sick. It's easier to pick a truck that matches your needs, and frankly, it's usually the small things that matter in big purchases.
