Styrefoam bits from AC Vents
We have a 2006 Roo, new to us last year - this was oour first year overwiintering a TT. I covered it with a fitted Tyvek cover. Winter in Maryland wasn;t too bad last year - not much snow, but quite a bit of rain.
Uncovered the Roo a month or so ago, cleaned the exterior, flushed and sanitized the water system - everything looks good.
Today was the first day I had an opportunity to turn on the fan/AC. When i did, a small amount of what looks like styrefoam bits cam out of the ceiling vents. Not much, and mostly the ones toward the front of the camper, but some from the one vent way in the back. No mouse turds, hair or grass - just some styrefoam "pellets" (Maybe a tablespoon all together...).
I took off the intake cover (inside the trailer) and the filter there, but didn't see anything sinister.
Anything to worry about, or is this normal after a winter storage??
