I've just added a bunch of insulation to the cockpit floor and firewall. I used 1/4" cork sheeting first (cos I had about 100sq ft of it in the garage) followed by some Amazon sticky foam stuff. Together, they effectively raised the floor level up about 3/4".
I'm sure there are fancier/pricier and no doubt "better" ways to do it, but what I did will definitely cut down on engine noise enough for my needs.
So I started thinking about the "other" engine compartment - the Onan.
Back of my coach retains the original Palm Beach arrangement, rear dinette with fold down beds. The Onan's house is under the driver's side seat and the "roof" is plain, un-insulated fiberglass. Seems to me I could shut that sucker up quite a bit adding some sound deadening material to the fiberglass areas under the driver's side bed and possibly behind the wall too.
Anyone done this? Good results?
