I used a sandwich layered foam/high density rubber material from a company
called soundown. They do marine acoustic materials. Since my onan box was
galvanized steel sheet metal and little else I removed it and made a wooden
box out of 1/2” plywood with 2”x2” boards cut in half length wise to create
triangular reinforcements of the sheets. Soundown had a foil faced material
which was screwed to the inside of the box.
If you do not have room inside the box the material could also be place on
the outside.
