Construction dust??

[Hmf23]

So as we approach our 1yr anniversary with our coach we've had many great adventures. We have had some issues none of them to major and Newmar has taken care of them all using a Tech Referenced shop here in Northern California. As we've used our coach I've cleaned up construction debris throughout the coach and basement area. My biggest issue or complaint is every time we run the A/C it leaves little white dust particles everywhere in the bedroom and rear bath. Its not outrageous but becoming very annoying to say the least. Has anyone else suffered from the A/C dust particle issue? Someone with recommendations on how to get ride of it or should I have it looked at before warranty is up? Thanks Brad

We just bought a used 2008 KSDP. If there was any dust in the air-conditioning ducts, it's long gone now.

However, the previous owner warned me that I'd need to replace the passenger cab audio speaker as it sounded awful. He said it was blown.

When I removed the last screw holding the speaker up, I was doused with sawdust! Brand new, very clean sawdust. At least a cup fell out. I reached my fingers around the top of the hole and scooped out nearly another cup!

The driver's side speaker had less, but still a lot.

I posted this observation here and was informed that it doesn't happen often, but every now and then the Newmar clean-up crew messes up. The last thing that's supposed to happen on the assembly line is a complete vacuuming and cleaning.

Another possibility with your coach is that a ventilation duct might have partially detatched. Or, you've got mice up there! That's no joke. Mice have chewed a couple of holes in the furnace ducts in the basement of our 5th Wheel trailer. They use them as raceways to get from one end of the coach to the other. Before one gets caught in a trap, our cats chase them from floor furnace duct to floor furnace duct following their sound in the ducts. The cats think this is great entertainment. Grrrrr.

Yes the clean up crew does a very thorough cleanup of the coach AFTER assembly. It’s what’s left behind panels is never caught. We had sawdust in our tank level display. When the tech took the display out to clean, sawdust poured out. We have found several places where painters tape was left on out of sight panels. One wad kept smearing glue from the tape on our tile floors every time the slide was operated. And the mystery bolts and screws kept showing up for over a year. If you buy a new coach, check for any dust around panels. Make the tech take the panel off and verify there is on hidden junk.
