Keep air circulating through your RV without letting in rain. This aerodynamic vent cover gives you the freedom to leave your RV roof vent open in any weather, when driving down the road, or when you're away from the RV.


The cover mounts to your vent frame, not your RV's roof, so you won't have to worry about leaks. Drill holes into your existing vent frame using a 3/16" drill bit, then attach the L-shaped mounting brackets using the included screws, nuts, and washers. The vent cover secures to the mounting brackets using carriage bolts. Simply slide the holes in the cover onto the bolts and tighten using the included washers and nuts.

Very fast delivery! Product matches the older vent cover that came with the RV, except it has two front screws instead of the clip latches the original had. The front screws work best for keeping the lid closed during travel though. The instruction manual was missing information past step 2, but luckily there was no need for instructions since this is a quick and simple, common sense job.

The vent cover arrived and I had it installed on my motorhome in just a few minutes. Since it was replacing a similar cover, I was able to use the brackets that were already in place. These covers perform as advertised. It's nice to be able to leave the vents open even when it's raining.

Ask the Experts about this Camco RV Vents and Fans

  • Why Aren't Roof Vent Lid Covers As Tall as Roof Lid When Fully Opened
    Roof vent covers like the part # CAM40421 aren't as tall as a roof vent lid when fully opened because with the vent style these fit the vent is basically at full functionality when the lid is only partially opened. In general these vents do not flow a crazy amount of air so the lid being opened at a lower angle wouldn't flow any less air than one opened all the way up.

  • How To Use a Roof Vent Cover With An Auto Open Roof Vent
    The tallest roof vent cover we offer in white is going to be the MaxxAir FanMate RV and Trailer Roof Vent Cover part # MA00-955001 which is about 10-1/4" at its highest point. I will say that most of the auto-open roof vents will stop raising when they sense resistance so you may still be able to use the above or the Camco Aero-Flo RV Roof Vent Cover w/ Swing Open Lid part # CAM40421 that you referenced. However, if your roof vent does not stop opening when sensing resistance then your...

  • Will Camco Aero-Flow RV Roof Vent Cover # CAM40421 Allow Roof Vent Lid to Open
    The 9 inch height of the Camco Aero-Flo RV Roof Vent Cover # CAM40421 does not allow roof vents to open all the way but the vent would still open far enough to get the needed airflow. I attached an install video for this cover for you to check out as well.

  • Will Mounting Hardware for Camco Aero-Flo RV Roof Vent Cover # CAM40421 Eventually Rust
    The mounting hardware that comes with Camco Aero-Flo RV Roof Vent Cover # CAM40421 will remain covered and protected from the elements most of the time. It can swing open for access to the vent but otherwise it is closed. Given enough time any hardware could start to form corrosion.

  • Replacement Vent Cover for Ventline VBO568 Dome Lid with Side Slider
    I may have a solution for you, but we don't have any roof vent covers that have the side slide that you're looking for and I can't say that I've seen anyone successfully modify these since the arms are riveted into the plastic. With that said, you could use the Camco Aero-Flo RV Roof Vent Cover w/ Swing Open Lid - White # CAM40421, which basically acts like 2nd cover and would allow your roof vent to remain open while still preventing rain from getting in. This solution would allow...

  • Is the Camco Aero-Flo RV Roof Vent Cover Available in Black
    We only have the Camco Aero-Flo RV Roof Vent Cover # CAM40421 in white but we do have the Camco RV and Enclosed Trailer Roof Vent Cover # CAM40443 in black which comes with a detachable screen so that you can easily get to your roof vent as well.

  • Is Caulk Neeeded When Installing Trailer Roof Vent Cover # CAM40421
    Since the Camco Aero-Flo Vent Cover attaches to the existing vent, you will not have any fasteners piercing your roof. Caulking would not hurt anything, but according to Camco, it's not necessary. If you click the provided link, you can see a video of the Aero-Flo vent cover being installed.

  • Can Camco UltraGuard Pop Up Cover CAM45764 be Used with Aero-Flo Vent Cover on Pop Up
    Yes, the pop up cover part # CAM45764 that you referenced will fit your 14.1 foot trailer that has the Camco Aero-Flo RV Roof Vent Cover # CAM40421 installed. The cover is designed to accommodate trailers that are up to a few feet longer than yours so it would accommodate the vent cover easily.

  • Recommended White RV Non-Powered Roof Vent
    I may have an option for you, but there I was unable to find any information on a 22.5" x 22.5" RV roof vent. The closest option we have is to install a standard RV roof vent like the Ventline E-Z Lift Ventadome Trailer Roof Vent # V3092-601-00 which is a non-powered roof vent, and the install the Camco Aero-Flo RV Roof Vent Cover w/ Swing Open Lid - White # CAM40421. The # CAM40421 will install to the frame of the roof vent and measures 22-1/2" x 20" and is the closest size we have...
