I recently purchased a used 2007 American Eagle 42V. Anytime I drive down a dusty dirt road, the inside of the RV immediately fills with airborne dust front to back. This is with All 3 rooftop A/Cs running and the dash A/C on or off. All doors and windows shut, vent fans off and shut. Where should I start looking for air leaks? I feel like the RV fills with dust before the dust level even reaches the roof, so I don't think it's roof A/C related.

We run the dash AC on the max setting with the fan on low, this kinda (pressurises) the cabin to keep out some of the dust. You might have a slideout seal folded or not sealing. Also check the removable floor section under the bed for leaks. Keep us posted with your results please.

Also check the seal around your refrigerator.

If you have an absorption fridge the back and ceiling vents are open to the outside. If the seal around the fridge is leaking, lots of dust from the outside could get in.

If aftermarket residential fridge(i.e., someone replaced the absorption unit with residential) look to see if the roof vent and access door vent are sealed.

If factory installed residential... you should have no leakes(no fridge vents).

WHEN TRAVELING ON DUSTY ROADS YOU WANT TO PRESSURIZE YOUR
MOTORHOME WITH CLEAN OUTSIDE AIR TO PREVENT THE DUST FROM BEING DRAWN IN THRU (SMALL OPENINGS)

You want the ceiling vents closed and the DASH Heater/Air Conditioning SET ON FRESH OUTSIDE AIR and the HIGHEST FAN SPEED WILL GIVE THE MAXIMUM BENEFIT

The maximum setting usually means RECIRCULATING the same dusty AIR over & over

If you have a slide out generator in the front, slide it out and check the seal of the coach that is behind the gen.

I'm confused, what seal?

Sorry, maybe a poor choice of words. On my coach, there are many misc wires, lines, hoses, etc that run through what would be the fire wall on a car or pick up, into the coach. You can see them by sliding the generator full forward and stepping into the space between the back of the gen and the fire wall. Several were not very well sealed, making it very drafty in the two front seats.

I just run the dash on "vent" or "Normal A/C" which opens the fresh air flap and turn the fan on high and that usually does the job. "MAX A/C" won't help.

If your roof ACs have any form of air exchange from inside to outside, then they are part of the problem.
If you run with a bathroom vent slightly open then that too is not helping.

Shut any interior doors and see if that confines the dust to one room and then you know where to look. I had dust coming up the rear cap and into the bedroom through gaps at the back of the bedside cupboards and past the ends of the bed platform hinge.
