We just arrived home after a grueling trip along the Alaska Highway that included many loose gravel sections and a roller coaster ride. We noticed that when we travelled through the gravel sections, there was a lot of dust that entered the cabin. Upon further investigation, I found that the basement door seals were leaking the dust throughout the basement area and it worked its way into the kitchen area mostly. We have a 35GS and would like to know if anyone out there has done modifications to the seals to avoid this issue. Plus our stored items in the basement were covered in dust. Thankfully I store most everything in plastic tubs with lids.

I believe that most of the dust comes in through the holes for the slide out axles that go between the bays. This hole is open to the road between the bays.
What I did was to cut some short pieces of 3in drain pipe and slit it long ways. I then slipped it over the axles and slid it through the hole so that it went from one bay to the other bay. I then filled the area around the pipe with expanding foam.
This should seal the bays form the road dust that comes up between the bays.
I also fill all the holes going form the bays up into the coach with the expanding foam. In the generator compartment, behind the refrigerator, and the heated ducting can all be sealed with the expanding foam.
I stay at the desert in the winter and we get allot of blowing sand and these fixes using the foam have just about stopped the dust and sand from entering the coach.
I had the same thing happen years ago on a gravel highway in BC in an older RV.....except it was inside the RV. Not sure you can do much about it. We had dust comeing in the back door around the seal.
Boat trailer fenders got the paint stripped too like they'd been through a sand blaster.
I like the blower idea. The dust did come in through the back via the low pressure area. Nice one, AKRV.
This may help, its the standard trick for this problem, like AKRV said, and that is to close up everything and turn on the trucks AC on high fan speed, but not recirc, if you have to, and this is a real problem, install a large fan it a sky light, to force more air in. The air from above the roof is a lot cleaner than from under the MH on a dirt or gravel road.
Hopefully you can pressurize the inside and get air to leak out, rather than come in with it's dust.

If there is dust flying all around you, aren't you just going to be bringing dusty outside air INSIDE the coach?????

That's why you want to use the blower fan in the cab. It brings air in from the front of the chassis before the wheels kick up the dust. Of course, if there's someone in front of you kicking up dust then there's not a lot you can do...
