  • This vent cover should not be used with high-powered ventilator fans.

MaxxAir Standard Installed Over Open MaxxFan

The MaxxAir standard vent cover installs over your roof vent so that the vent can be opened and the fan can be operated in any weather. This prevents heat from building up inside your RV or trailer and allows smoke and stale air to escape, while also keeping rainwater and debris out. A removable bug screen behind the louvered area helps prevent insects from getting in. Zero-Leak brackets are included for installation.


Zero-Leak Mounting Kit

The Zero-Leak installation kit included with this vent cover prevents leaks by eliminating the need to drill into the roof of your RV or trailer.


Installed ZeroLeak Kit

Instead of mounting to your roof, this vent cover mounts to the frame of your roof vent. Simply drill 4 holes into the vertical frame of your roof vent so that you can install the Zero-Leak mounting brackets. These holes will be hidden underneath the vent cover once it is installed, where they will be protected from the elements.


If you are installing this vent cover over a Ventline E-Z Lift Ventadome roof vent, then drilling is not required. The E-Z Lift vent has mounting tabs with pre-drilled holes for installing the included hardware.


The kit comes with rustproof aluminum brackets and stainless steel screws, bolts, nuts, and washers.


Durable Construction

Durable Construction of MaxxAir Standard

This vent cover is constructed of durable, high-density polyethylene. Special additives help ensure that the material can resist the negative effects of UV rays. And the cover is translucent so that some natural light can shine through.

We needed some MaxxAirs for a new 5th wheel that we purchased. We knew from having them on a previous camper that they are good products. eTrailer has been a trustworthy place to order and get knowledgeable information from in the past. I had found a really good deal on the MaxxAirs at a different site, and contacted eTrailer. They stuck to their 110% price match policy and beat the other price. Quick shipping and good service on top of the best price. Can't beat it! 343886

After viewing the installation video and thoroughly reading the instructions the installation was a breeze. Had it done in an hour with the exception of having to go to the house to get a missing lock washer that was overlooked by the factory. Also the included flat washers were to large in circumfence so I had to replace them with smaller ones from my stash. The hood louvers deflect rain as advertised and the screen inside the hood repels bugs and dust. The hood mounts solid and the quality is awesome. I expect many years of dependable service and the price was great. I combined this hood order with a Max Air II and am satisfied with both. 283122

The max air vent covers are the best. Easy installation and are screened which not only helps keep the bugs out but also helps stop the rain. Should keep the camping hauler a little cooler and drier. The tarp is just to keep the sun off. 564609

E-Trailer comes through again. I bought with confidence here after making a few previous and flawless purchases. This time the box was short one vent cover, a quick email with pictures of box and a phone call and my missing cover was on its way. Thanks for the quick painless resolution. As for the covers, plastic as most things these days but installed with confidence knowing they would do their job. Install was easy and straight forward even with my Lance 1575 "no walk on roof". Sat on edge and was able to do what needed to get done-center cover over vent, mark holes, drill holes, put brackets in place and bolt down. Easy as it gets and now fresh air in the rain is a crank turn or two away. The wife and I made a weekend of this and sealed roof while up there. Camping season, we are ready. Thanks E-trailer and MaxAir!! 497207

Good product and it was pretty easy to install. I put on 2 in less than 1 hour. Love that I can now open the vents even if it's raining outside and nobody gets wet and I can run down the road with the vents open to keep our 5er cool. 817931

This was a breeze to install. I did bring my tool bag with everything i needed, but only had to go down once to slightly close the lid as it was to open. I was in the midst of washing clothes so had my timer on already so I was able to note how long it took. it didn't even take more then 15minutes to install maybe faster on my next one as i was moving slow. Thank you E-trailer for the how-to videos. I'm sure my father was smiling down from heaven seeing his little girl taking care of the RV on her own. <3 So satisfied with the product I am ordering a few more for my other vents 810020

After purchasing and installing a new bathroom vent fan along with the proper garnish, I realized I should have replaced the vent hood. Ordered and received yesterday. The fan was a perfect fit and installed in 30 minutes when last week. Well, the hood was a 10 minute job (5 of them getting on the roof). I will fill my RV parts needs using etrailer products, in the future and will recommend them to other Resort residents without hesitation. 797624

  • What is the Difference Between the MaxxAir and Camco RV Vent Covers

The overall dimensions of the MaxxAir is 19" long x 18-1/2" wide x 9-1/2" tall and the overall dimension of the Camco RV is 18-1/2" long x 18" wide x 9-1/2" tall.

  • Which MaxxAir Roof Vent Cover Fits Ventline Roof Vents # V2128sp-01 or # V2092sp-28
    The vent cover # MA00-933066 is designed to basically fit any roof vent so it would be the one to use with either the part # V2128sp-01 or # V2092sp-28 that you are wanting. The Camco Vent Cover part # CAM40431 is also an option that would work too. The part # MA00-933072 requires a MaxxAir roof vent since it has install brackets that match that roof vent so it would not be the correct part for you to use.

    While the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 isn't designed specifically to be hail resistant if you found yourself in a hail situation where the hail was big enough to damage the cover you'd also be damaging the roof of the trailer.

  • Picking Out Roof Vent for 2004 Alumascape Travel Trailer
    Most likely we have what you are looking for but you will need to first determine what vent you have on your trailer. The best way to find the correct replacement vent cover for your cargo trailer is to measure the vent. Most standard vents are 14-1/4 by 14-1/4 inches wide, 14 x 14 inches wide or 13 x 14 inches wide. Next if the manufacturer name is on the vent that will help. Finally, you will need to look closely at the hinged portion of the vent. If there is a rolled metal hinge...

  • Availability of Replacement and Upgrade Parts for 2002 Holiday Rambler Alumascape Travel Trailer
    The series name for a travel trailer (and the specific trailer's VIN) are helpful when communicating with the trailer's original manufacturer but in terms of finding replacement parts you really do not need these. This is because most trailer makers do not maintain records of smaller component parts, such as wheel bearings for example, that are used in fabrication of their trailers. So finding replacements for worn items - or even upgrades - will just be a matter of telling us what you...

  • Can Maxxair Roof Vent Cover MA00-933066 Fit Forest River R-Pod 178
    On the Forest River R-Pod 178s the center section of the roof is fairly flat so if a standard 14 x 14-inch roof vent is installed then you should not have any trouble installing a vent cover like the MaxxAir # MA00-933066. This cover attaches to the existing vent assembly, NOT to the trailer's actual roof surface, so you do not need to drill holes in the camper's roof. Slight curvature of the roof will not prevent installation since the cover connects to the existing vent. You can refer...

  • Replacement Vent Cover for a 2001 Four Winds Majestic Flyer Motorhome
    If you are talking about a roof vent cover to help keep the rain out then I recommend going with the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 because it is a universal application and mounts to the frame of your trailer roof vent. For a replacement lid you will simply need to note what kind of hinge your roof vent uses. For a continuous hinge I recommend the Ventline # BV0554-01, for a 3-point hinge I recommend the Ventmate # 69284, and for a 4-point hinge I recommend...

  • What Vent Lid Cover Can be Used with Unknown Vent in Hitchhiker 5th Wheel

I attached a review video for this that shows how it installs as well. We have some vent covers which are vent model specific but I'd need to know for sure what vent you have now.

  • How to Pick Out Replacement Hardware for Maxxair Vent Covers

If instead you got the standard MaxxAir vent cover like the part # MA00-933066 you'd want the # MA00-225000.

    For your Ventline Ventadome, you will want the Replacement Dome Assembly for Ventline Ventadome Trailer Roof Vent # BVD0449-A01 or # BVD0449-A03 which is confirmed to fit your Ventline model. If you are looking for a rain cover compatible with this vent, I recommend the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066. This will give you the mounting hardware and cover to allow use of your vent in less ideal weather. Since you don't have the factory mounting locations,...

    The MaxxAir Mini Trailer Roof Vent # MA00-03700 that you referenced is made out of a durable plastic that actually does a really good job against the sun. If you wanted a total metal vent then you could use the Ventline Ventadome Trailer Roof Vent # V2110SP-24 which is also a manually operated vent. The thing about this kit though is that it will keep out bugs and debris when left open but not rain. To keep it open while it is raining you would need to use a cover like the MaxxAir Standard...

This cover will allow for full vent function and also allow the vent to be open when traveling or camping in the rain. This is also available in smoke # MA00-933067. These covers will not require any additional mounting location but utilize the vent itself.

Part # MA00-933066, for example, measures 19-1/2L x 18-1/2W while cover # MA00-933067 measures 18-3/4L x 19W Inch. I went to our warehouse to measure these brackets for you.

The vent is very low powered, and is designed to provide a small amount of ventilation to draw odors from the stack on a black water tank on an RV. It wouldn't have enough draw to do much to lower the temperature in your trailer. I'd recommend installing a vent cover like # MA00-933066 which is compatible with standard 14 x 14 roof vents. With this in place, you could leave existing roof vent...

The covers we offer for the Maxxair standard vents are part # MA00-933067 for the smoke colored, and # MA00-933066 for white. As far as the smoke allowing in more light we have not been given those stats. The White cover is a more translucent cover and the smoke colored cover is a more transparent cover.
