MAXXAIR Maxx II 00-933081 Vent Cover - Wind Resistant Roof Vent

Our review of the MAXXAIR Maxx II vent cover finds it is a practical upgrade for RV owners who want constant airflow without letting rain, bugs, or debris inside. The single biggest reason to buy is its proven one-piece, high density polyethylene construction that delivers durable, UV-protected performance and a sleek aerodynamic profile that reduces wind resistance while keeping vents open in poor weather. Installation is straightforward for most standard 14 in x 14 in roof vents, and the cover's design maintains fresh air flow without compromising protection.

Key Features

• One-piece construction: The super tough, single-piece design provides long-lasting protection and resists cracking or splitting under normal road and weather exposure.
• Weather protection: The cover keeps rain, leaves and bugs out while still allowing stale air and cooking odors to escape from the RV interior.
• Aerodynamic shape: A sleek profile reduces wind resistance and minimizes turbulence around the vent while driving or parked in windy conditions.
• UV-stable material: Made from high density polyethylene with maximum UV protection to prevent sun damage and fading over years of use.
• Zero-Leak mounting: Compatible with most 14 in x 14 in standard vents and features a mounting method that avoids drilling through the RV roof surface.
• Six-year warranty: Backed by a 6 year limited warranty for added peace of mind on durability.

Who It's For

The Maxx II is best for RV owners who use roof vents regularly and want reliable ventilation in wet or buggy conditions; it is especially useful for those concerned about heat build-up and interior odors since it provides constant airflow while blocking the elements. It also suits owners who prefer a clean, white, low-profile look that blends with most RV roofs and who value a mounting system that minimizes roof penetrations.

Those who should look elsewhere are owners with nonstandard vent dimensions or those who specifically need a cover engineered for a different brand's unique fan mounting pattern; some customers report fit issues with certain original fan models. If your vent is not the common 14 in x 14 in size, confirm compatibility before purchasing.
