Measurements of Mounting Points for MaxxAir Standard

Notes:

  • 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 have used these before, and the pair I installed a year ago has held up very well in the weather. I used less expensive brands, and they deteriorated to the point of extreme fragility within a couple of years. I have two standard cheap fans, not Fantastic Fans. The fan shrouds don’t open quite completely under the covers, but the slightly reduced ventilation area is minimal. This limitation is far outweighed by the ability to open the fan shrouds when it’s raining. I recommend these to everyone wanting a vent cover, and that should be everyone who owns an RV. I do not understand why manufacturers do not make vent covers original equipment.

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!

It has continued to work well. Glad we we bought them...

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!!

etrailer has the right products at a good price. Their product descriptions are clear. They shipped my order within a few days of placing it. I got it the day they said. I will use them again!

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.

Delivered quickly and product is already installed. Fits great. Thank you for having all the helpful info in your website. Allows me to leave vents slightly open during summertime storage without worry of rain Thanks

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.



- MA00-933066
by:

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.



- MA00-933066
by:

Product quality and instructions are excellent. This was ordered as a fall project prior to winter snows to protect the factory 14x14 vent. Year-round air flow within the enclosed trailer should be very good while traveling.

Have never had any issues with ordering anything from etrailer! When it comes time to update items on our Motorhome I always think of etrailer, items ordered shipped in a timely manor and arrive in excellent condition!

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

looked for some time trying to find the right part. We are restoring our 94 Allegro Bay. The parts person at Allegro refered us to you. Great move on his part. thanks again!



- MA00-933066

Fantastic! Very nice add when the summer months are so hot and we can leave the vents open while traveling so the RV isn't near as hot and cools down quickly.



- MA00-933066

Replaced my old ones which were black in color. These allow a little more light in to brighten things up. They are nice also because you can leave your vents open regardless of rain or driving.

The vent came as advertised. It was easy to install. The quality of the vent is great. I have had it now for a year and it still looks like the day it was shipped to me. The price was right and I definitely would recommend this product and e-trailer to everyone.

Great product but could use a lot better packaging, they used a very odd shaped box that was not even close to big enough for the product.

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.

Product looks and feels well made. Came with easy to understand instructions. Installation was simple and quick.

  • 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...

    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 attached...

  • 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 Correctly Measure RV Vent Opening
    In order to properly measure your RV's vents, you will want to measure the size of the rough opening in your RV's roof. This can be measured by removing the garnish around the vent on the inside of the RV and measuring the size of the rough opening. The most common RV vent's measurements are 14" x 14" like the MaxxFan Deluxe Roof Vent w/ 12V Fan and Thermostat # MA00-06200K.

  • 15 x 15 RV Vent Cover Replacement Recommendation

This cover goes over the vent unit completely to allow you to use the vent in any weather.

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.

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...
