Keep air moving through your RV no matter what the weather is doing. The Camco 40453 vent cover in smoke finish mounts over your existing 14x14 roof vent and lets you leave it open through rain, light wind, and road travel -- without letting in water, bugs, or road debris. The aerodynamic one-sided vented design sheds water while maintaining strong airflow, and the removable louvers make seasonal cleaning a five-minute job.
Standard RV roof vents are all-or-nothing: open for airflow, closed for weather protection. The Camco 40453 breaks that tradeoff. Its raised aerodynamic housing lets you leave your vent open during rain showers or while driving, pulling stale air and heat out of your rig without letting water in. The smoke-tinted finish blends naturally with most RV rooflines and resists sun fading through UV-stabilized construction.
Whether you are a full-timer managing interior climate daily or a weekend warrior who wants the rig aired out on the drive home, this cover earns its keep on the roof all season long.
Louvers lift out for quick cleaning -- no tools needed. Flush out pollen, dust, and debris in minutes.
Integrated mesh screen keeps flies, mosquitoes, and other insects out while ventilation stays unrestricted.
Material is formulated to resist UV degradation, preventing yellowing, cracking, and brittleness after seasons of rooftop sun exposure.
Aerodynamic one-sided vented housing sheds rain and road splash, letting you ventilate during showers without water intrusion.
The directional vent design channels airflow while deflecting precipitation. Most RV owners report being able to leave the vent cracked open on rainy travel days, reducing interior moisture and heat buildup without water damage to walls or ceiling panels.
This cover is vented on one side only. For best performance, orient the open side away from your typical direction of travel so wind pressure assists exhaust airflow rather than forcing air inward. Confirm your roof vent opening measures 14 inches x 14 inches before ordering -- this is the standard size for the vast majority of OEM RV roof vents, but a small number of older or specialty rigs use different dimensions.
The cover mounts to the existing 14x14 vent frame using the frame's existing flange. Most installations require a bead of self-leveling lap sealant around the base perimeter to prevent water intrusion under the mounting flange -- lap sealant is not included. Inspect your roof surface around the vent before installation. The cover does not replace or repair a damaged vent lid; it mounts over an intact vent assembly.
