Never seen this type of ductwork

I think it’s a high velocity air system.

Agree.

@jmckee

things keep changing, it is often hard to keep up

I have posted links about them for a couple of years now, and again just a few days ago.
Surprisingly, they seem to be mostly ignored.

Return air vent?

I haven’t seen one installed in a Manufactured Home (yet), but I could see the benefit of that home having a Hi-Velocity System installed, especially if it’s a larger home. Would simplify the Supply Duct system with the thinner wall/ceiling areas available in a MH. [e740879ecefbd2ffe4771687ae141d0811483f55]
