Tom,
You may want to start by duplicating a few of the things we did:
A. Remove the grills (they have protrusions on the bottom that simply insert into holes - 2 per grill).
B. Apply felt or rubber stick-on patches:
1. Behind the lower rail of the blinds and shades (which stops them from bumping metal to wall),
2. At all contact points of the counter extension (including the metal arms),
3. Between the cabinet doors and frame,
4. Between the back of the screen door and mounting frame.
5. At the sides between the upper metal part of the blinds and mounting frame.
6. On the antenna between any close points and roof.
C. Do not place anything hard at the bottom of the cabinets or drawers.
D. Wrap glass items in a paper towel before placing them in the drawers.
E. Place a soft item between pots & pans, etc.
F. Wiggle the vinyl-covered shelves over the Driver and Passenger seats. If they squeak, a little tightening could be in order (pry off the button to expose the screw head).
I'm really very bad with strange noises and drive Peg nuts with them. But she's been a good sport and has been quite successful chasing the noises I object to. Now, unless we are on a bad road surface, our rig is almost as quiet as our Edge and Mercury cars, which is saying something.
Regardless of the above, there will probably be noises that simply cannot be eliminated.
