Dust is dust. Doesn't matter if it's kicked up by wind or thrown up by tires.
Dust is dry particulate matter ranging in size from 50 to 10 microns, meaning that individual dust particles are too small to see with the human eye. Airborne dust looks like a cloud of dirty air and it's pervasive; it can get in anywhere that air can. You can see piles of dust or a film of dust, but not individual dust particles. Any cloth (or a HEPA vacuum filter) that has openings smaller than 10 microns (microfiber) can pick up dry dust. Anything with larger opening sizes will just stir it up.
Wet dust is easier to pick up than dry dust. This is where Lemon Pledge comes into its own. Spraying the dusty surfaces coats the dust particles and makes them bigger, as well as making the dust particles stickier so that you don't need microfiber to pick up the dust.
The only way to block dust from getting into your trailer in the first place is to seal every opening where air can get inó including your roof vent. Or to avoid parts of the country where you can encounter airborne dust.
