Somethings not right. Air gets sucked into the truck from the cowling right under the windsheild. Behind the GBox is the cabin filter.
Even if you are sucking dust in (like from following soemone else, or coming to an abrute stop), and you didn't have filters the dust would come out the vents. I would check to make sure that the filter box is sealed up properly. Someone could have changed out the filter and not closed up the box right. And you are getting blow by.
