    EVERY TIME I DRIVE THE RV AND A CHANGE IN TEMPERATURE AND HUMIDITY OCCURS THE WINDSHIELD AND BOTH SIDE WINDOWS FOG VERY BAD, THEY WILL NOT DEFROST AND YOU CANNOT SEE WHILE DRIVING DOWN THE ROAD, YOU CANNOT SEE THROUGH THE MIRRORS ON EITHER SIDE BECAUSE OF THIS, IT DOES NOT MATTER WHAT ROAD YOU ARE ON. NOT ENOUGH AIRFLOW FROM THE DEFROSTER AND NOT ENOUGH VENTS ON THE FRONT WINDSHIELD, IT HAS NO SIDE VENTS AT ALL. I HAVE REPORTED TO THE MANUFACTURE BEFORE AND THEY SAY IT MEETS THE INDUSTRY STANDARDS. *TR
