CamcoFits 14 x 14 in. VentsUV-Resistant ABSCamco XLT RV Roof Vent Cover II -- White (Part 40446)

An oversized, aerodynamic replacement vent cover that installs over your existing 14 x 14 inch RV roof vent opening. Keeps rain, debris, and road grime out while letting air flow through -- even while driving. Compatible with manual and powered vent fans.

Keep Air Moving and Weather Out -- Without Replacing Your Whole Vent

The Camco XLT Vent Cover II is purpose-built for RVers who want better airflow and weather protection without a full vent replacement. Its oversized dome clears most powered fan blades and vent mechanisms, giving you the clearance needed to leave the vent cracked open in rain -- a feature standard covers simply don't offer.

The aerodynamic low-profile shape reduces wind noise and drag at highway speeds. Pivoting louvers on the rear grate open and close to control airflow direction and block wind-driven rain from getting in. The entire cover opens for easy cleaning and maintenance access without tools.

Pivoting Louver Grate

Rear grate with adjustable pivoting louvers lets you direct airflow and block wind-driven rain without fully closing the vent.

Oversized Dome Clearance

At 25 x 19.5 x 11.5 inches, the dome provides enough interior clearance to work with powered vent fans and Fan-Tastic/Maxxair-style units.

UV-Resistant Material

White ABS plastic resists sun-induced yellowing, cracking, and brittleness -- critical for covers that sit exposed on a roof year-round.

Hardware Included

Comes with mounting hardware and fits most existing 14 x 14 in. mounting bracket footprints, making direct replacement straightforward.

Airflow Without the Weather Headache

One of the most common complaints among RV owners is having to close the vent the moment it starts raining -- losing ventilation right when humidity and condensation are building up inside. The XLT Vent Cover II solves this by creating a protected air channel that lets fresh air in and stale air out even during light rain or drizzle.

Works With Powered Vents: The oversize interior height accommodates powered fans including Fan-Tastic Vent and Maxxair-style units. The dome sits well above the fan blade plane, eliminating the interference that causes wind noise or restricted rotation on tighter-fitting covers.

Installation -- Replacing an Existing Cover

The XLT Cover II is designed to mount directly to standard 14 x 14 inch vent flanges and is compatible with most existing mounting bracket configurations, so you typically won't need to drill new holes. The mounting hardware is included in the box.

  • Remove the old vent cover by unscrewing the mounting fasteners at each corner
  • Position the XLT Cover II over the vent opening, aligning the base feet with the existing holes or bracket
  • Secure with the included hardware -- no special tools required
  • The rear grate snaps into place; pivoting louvers are already assembled
Replacement Note: Fits most existing 14 x 14 in. mounting bracket patterns. If your current vent cover uses a non-standard bracket spacing or a raised curb mount, verify the base footprint before ordering. Most OEM vent flanges on Class A, Class C, fifth wheels, and travel trailers are compatible.

Cleaning and Maintenance

Maintenance Tips:
  • The cover opens for full interior access -- clean debris, insect nests, and road film from inside the dome without removing from the roof
  • Wipe down with mild soap and water; avoid abrasive cleaners that can scratch or cloud the surface
  • Inspect the pivoting louvers seasonally to confirm they pivot freely and seat correctly when closed
  • Check mounting fasteners each spring if the rig is stored outdoors in freeze-thaw climates

Important Information
  • Designed for 14 x 14 in. standard RV roof vent openings only -- verify your vent size before installing.
  • Not intended for vents with raised curb heights significantly above standard flange height without additional adapter hardware.
  • Do not use power washers directly on the cover -- high-pressure water can force water past the louvers and into the vent opening.
  • Inspect the roof sealant around the vent flange when installing -- this cover does not reseal or weatherproof a compromised flange.
  • UV resistance slows degradation but does not eliminate it entirely in extreme desert climates -- inspect annually for surface cracking.
