Pete,

Getting dust in from poor seals around the wheel wells can be resolved 
with shims, blocks, rivets, and caulk. It's more difficult, IMHO, to 
stop leaks through windows and access doors. I don't know if this is a 
surprise, but the air flow around an Airstream has low pressure on the 
sides and top and high pressure at the butt end. Really. You will find 
that the worst dust ingestion is through the back window or rear access 
door. When I go down dirt roads, I use duct tape around the window and 
door to ensure a total seal.

If you don't see dust around the other windows or door, it's because 
they are in low pressure areas and the interior air is actually going 
out past their edges if they aren't fully sealed. So you usually find 
less or no dust there. And they are acting as vacuums to pull the air in 
through poor rear end seals.
