I'm also considering putting something under the rubber flooring. Carpet won't work for me. I need an easier to clean surface.

You bring up an interesting point, one I hadn't considered. After reading your post, I went online and read some of the articles pertaining to the issue of heat wrap causing premature wear or damage of exhaust components.
While I never personally experienced any of the problems described, I can see how the wrap could cause potential problems... particularly with a motorhome application.
I see that part of the problem would be lack of sufficient airflow around the exhaust in the doghouse, could very well lead to temperatures exceeding the systems thermal capacities... especially in a situation such as a long climb, where exhaust temperatures can soar.
I re-thought my suggestion and would NOT recommend using the wrap as a remedy for the issue discussed here.
In my situation, the headers and exhaust system were right out in the air stream, which probably mitigated issues with heat soak.
