I used closed cell foam and covered that with a sound deadening foil backed
material that felt a lot like lead. It is made for hot rods to deaden
sounds from exhaust systems, etc. It is heavy but really effective. It
quieted that Onan down a lot. Can't remember the trade name. Summit has it,
as well as other suppliers.
