MaxxAir ventRVers know to open roof vents aboard their rig to keep temperatures down and musty air out. However, they may not always remember to close them, which may lead to a soaked interior if it rains. With MaxxAir Vent Corp.’s Original MaxxAir Vent Cover installed, owners can leave their roof vent open all the time, while still protecting the cabin from rain damage, according to a news release. Having a roof vent open lets fresh air in and allows odors to escape. America’s first choice for RV ventilation, the MaxxAir vent cover provides constant airflow and prevents heat build-up. It also lets musty air, smoke and cooking odors escape for a more pleasant indoor environment. It easily installs over all popular, 14″by 14″ standard roof vents. Featuring an exclusive Zero-Leak Mounting System, there’s no need to drill any holes in the RV’s roof surface. The MaxxAir Original features a proven, tough one-piece design and carries an industry-leading six-year warranty. Each unit measures 19 1/2 inches long by  18 1/2 inches wide by 9 inches high.
