I think you might find that road sand is being sucked up inside the rear cap. There is a lot of turbulence that creates a vacuum in the rear of a motorhome while moving down the highway. The sand is being sucked up and getting trapped between the roof and ceiling moving forward to the front of your coach.
Same thing happened to me recently but the sand was ending up in my rear bath cabinet drawers. I was lucky as there was enough room for me to get in there and seal the gap. Problem solved.
The trouble with that theory is, he's getting it INSIDE his A/C ducts. Even if the roof was completely open, front to back, the sand cannot get into the ducting due to it being a sealed (or supposed to be) system. And, for sand to travel, in between the top of the ceiling, and the bottom side of the roof, is highly unlikely due to the technique of construction.
