I am thinking about using a commercial roofing material on the outside of my TD,,its called TPO generically and is tough stuff,,,has anyone thought of using such a material or has anyone heard of it being used,,,its an easy material to work with and is available in roll sizes plenty large enough to accomadate odd size tears,,,may try it if no one has had any experience as a good alternative to metal,,,I know ya'll got openions so let me have them,,,thanks,,,,
