Measurements of Mounting Points for MaxxAir Standard


  • Some vents may not open fully when used with this vent cover. If opened 50% or more, the vent will still achieve maximum airflow.
  • This vent cover should not be used with high-powered ventilator fans like MaxxFan, MaxxFan Plus, ShurFlo Fan, or Fantastic Fan.

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.

I live in the desert and so far the desert sun does not seem to have affected them! I installed them because the desert afternoon breezes tend to damage and Rip vent covers off. 902836

Excellent equipment. I can now drive with a vent open with no rattling or fear of wind tearing the vent cover off. Great for warm days that are not hot enough for the air conditioner but too warm without having a vent open! 882541

Easy install and work great. HD plastic should last the life of the trailer. 861749

- MA00-933066

I am pretty happy with these! Ordered two, installed just fine on the enclosed trailer. NOTE!!! The "screen" that came with them is not the one pictured, its a course plastic screen, holes are like 3/16" square, not expected, but I am ok with it. 854784

Seen same product on other sites for much more money. Great vent cover, have several that are 15 years old on my travel trailer. This one is going on the enclosed trailer. 851528

Great product. Easy to install. Everything came in and it was packaged properly which is nice to see. On time. At a great price. 828362

- MA00-933066

The instruction page told me what the web page didn't - this is not the cover for a Fantastic Fan like I have in my 2002 Casita. :( But I had already received it and I'm in a rural area so sending it back isn't easy. So I took the Fantastic Fan's vent cover off since it wouldn't open up all of the way and took the control panel off to put the mounting bracket screws through. It appears that it will work now, but I'll have to rig up an indoor cover for cold weather. The FF cover let out lots of heat anyway so I'll make some kind of insulated cover. 822259

- MA00-933066

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

- MA00-933066

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

- MA00-933066

Order came quickly, packaging was strong, not the cheap cardboard often used, well packed inside, parts were well made. No complaints at all. Will go back to this company. 815543

- MA00-933066

Form , Fit and Function all worked well, had a hail storm and no issues, seals water tight. 808889

- MA00-933066

Came with all the brackets and fasteners to install on my trailer. Just follow the instruction. Took about 20 minutes to install and fit great. Now I can run and park my trailer with my vent open to keep my trailer cool inside. 807174

  • 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...

  • 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.

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.

    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.

  • 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...

  • 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...

  • How to Pick Out Replacement Hardware for Maxxair Vent Covers
    You didn't mention what kind of MaxxAir vent hood you bought, but if it matches the picture I attached in shape (not color as there are a few options), the hardwdare kit part # MA10A20115 that you referenced would be the correct kit. If instead you got the standard MaxxAir vent cover like the part # MA00-933066 you'd want the # MA00-225000.

    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...

  • Installing Vent in 6x12 Enclosed Cargo Trailer To Keep Interior Cool When in Storage
    The # UF53-945001 solar-powered plumbing vent probably won't do what you're looking to achieve. 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.
