Dust getting into coach on dirt roads

[Lindenberg]

This past weekend I drove down a dirt road and had quiet a bit of dust in the air inside the coach. All the doors, vents and windows were closed so I figured it must have come from the dash air vents. I had the dash vents turned off but wondered if the better way would have been to have the vent on and set to recirculate. Are there any other areas where dust can enter the coach?

Tom and Laurel,

Dixie and I have gone to Burning Man twice now. You don't know dirt/dust until you have been there, it is held on a dry lake bed.

On the first trip I found that with everything closed and off, dust would still infiltrate MANY places. I found that it helped to keep everything closed and off except for the front roof vent which I set to blow into the coach.

On the second trip I went one step better and built a box above that roof vent that had a filter mounted behind the vent and angled down so that the air was drawn up through the filter. This drew in filtered air and pressurized the coach so that most of the dust was kept out.

I haven't used this since, but will if I can talk Dixie into going again this year. My recommendation and what I try very hard to do, is to stay off dirt roads.

I like the heater/air conditioning/vent fan ON approach. The positive (outward) pressure of the air flow is the same principle used by the military to keep NBC (Nuclear, Biological Chemical) agents from entering a non air tight truck cab, APC, tank, etc. The only dust that should come in is that drawn in by the fan itself, otherwise the air flow (on a high setting) should be sufficent to keep dust from coming in around the vents, windows, doors, etc.....Harold
