It looks like it belongs there. So you are saying it doesn't?
Nope, not saying that at all.
In the ducted air on my trailer model, it "looks like" they simply put tunnels in the roof insulation to act as ducts to the round vents for my air flow, then didn't completely coat or line those tunnels in the styrofoam-like insulation so that bits and pieces won't flake off and blow out.
If that's the case, I suspect they may use that kind of cost effective short-cut on other ducted air models too.
The result on my trailer model is "snowing" of the styrofoam-like beads from the ducts and occasional flaked-off chunks appearing. Not a lot, just enough to notice some here and there each trip. Figure it will stop after a while, just a break-in thing.
I thought this initial "snow" effect (attached a sample pic) would be common with the duct design I'm seeing. Maybe I'm the only one experiencing this?
