You may want to try using a hair dryer on low temp to see if you can get the ceiling foam to relax a little more. If that does not work if you are good with wood you could use wood trim to fill in the dents.

I put mothballs in a paper cereal bowl and place the bowls on top of the tires, not inside the coach. I use Irish Spring soap bars, cut them in half and place them around the coach, mice hate that smell but humans like it. I place them in the closet areas, behind the sofas, etc. I use about 4 bars. My first year I thought folks told me Ivory soap, big mistake, the mice ate the soap bars, Ha.
