JoJim, If you have Fantisic Fans in your coach they do not reverse. Ed.S </div></BLOCKQUOTE>
At the GNR of Winnebago last week, the Fantastic Fan people were there and gave out free switches for the fans which would reverse the air flow into the coach. I inquired as to why that would be desirable and found out one good reason they propounded was in case of driving down a dirt or dusty road, the fan could be utilized to create a postive pressure in the coach to prevent dust from so readily coming in through crevices, etc.
As to why some motorhome builders do not put them in as OEM, it boils down to costs and RVIA standards it was explained.
They did not recommend putting the reverse switch on the Fantastic Fan in the john area where odors could be brought back into the rig from above the black tank vent.
