My 2018 model MicroLite came with about a gallon of sawdust included at no charge. Pretty much evenly divided among all storage compartments as well as hidden spaces. After a week of work with a vacuum cleaner I THOUGHT I had it cleaned up.
Foolish thought as road vibration kept shaking more and more out of nooks and crannies.
It's been 5 years since I brought it home along with approximately 40,000 or so miles I think it is NOW all gone.
When I red "beige, granular, substance", that's exactly what I found.
Sawdust is pretty easy to "diagnose". Fill a bowl with water, spread some on top of the water, and leave overnight. If sawdust it will first float, and with time the granules will swell up much larger.
Since it's a Rockwood, a Forest River product, my money is on "sawdust". They find it easier to just leave in their finished products rather than increase the amount of waste they have to pay disposal fees on.
