Thermosans were around in the late 1970's. I have never seen or heard of it after 1980. I have been a RV tech since 1979 and have only seen just one. That was in 1979. I "think" it was on a 77 or 78 GMC motorhome. They were aftermarket. Urban legends always seem to include a Hi level Gov. official. NOT practical with todays market and designs. Besides, I am sure it would violate numerous EPA type laws and regulations. Doug
