The pillow thingie is a vent insulating pillow 14"x14"x3". You stuff it in the vent opening and it insulates the area above it. Just go to Amazon and put in "rv vent pillow".
And come on, pictures of a piece of foam cut to block off the duct end runs? I bet it is a rectangular piece cut from sheet foam about the exact size of the duct run.
