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. 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.

Before I installed both vent covers I took picks and then the installed both took about an hour and a half. Everything worked out great as a matter of fact I can open both vent tops all the way. Here are some picks. All installation instructions were dead on Video was the best. Thanks ,job well done on both ends.



by:

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...



by:

This vent cover arrived in perfect shape and was very straightforward to install. Product seems very well made and will allow us to have the vent open while traveling without the worry of leaves or rain coming into our motorhome.



by:

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



by:

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.



by:

Haven’t had a chance to install but arrived missing carriage bolts on one unit. One neatly packaged and attached the other scattered throughout the box. No damage to the box from shipping. It appears to have been packed at the warehouse that way.

We recently sent you a new hardware and were wondering if you had any feedback about the the vent cover for other shoppers?



by:

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.



by:

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!!



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.



by:

Great quality for a good price, haven’t installed them yet but I’m sure I will be happy



by:

It was delivered perfectly and I am ready to install them. Thank you for checking with me



by:

etrailer has always been great. Product is packaged and mailed in safe,sturdy boxes, always on time, everytime just like they promised. I really like using etrailer more than other suppliers



by:

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.



by:

The Vent cover arrived promptly, and was packaged very well. We have not yet installed it but intend to do so soon.



by:

The roof vent cover for our Fantastic Fan has been an excellent buy. Etrailer was very easy to work with and very accommodating. It w quite easy to install, looks nice and it protects the vent from wind and rain when open. Highly recommend it!



by:

Great fit and product Excellent service and shipping



by:

These were pretty easy to install. Thankful we can keep the vents open when it rains. Have to close them sometimes when it rains hard, or when it's a blowing rain, but we've never had to close them completely.
I am thankful the website provides as much information as it does. Otherwise, I would have bought the wrong cover for the Northern Breeze powered vent.



by:

Thank you the new vent covers were easy to install and it went very well. Had all e done in 15 min.



by:

Great product, great quality



by:

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!

Awesome!



by:

These covers are a savior for RV's - they help keep rain out while allowing air to flow through an open vent.
They are made of great quality and come with needed hardware for simple installation



by:

Fast shipping and easy to install product on my RV. Looks great will buy again.

Very well



by:

The upgrades to my enclosed trailer looks good. I ordered several different parts from etrailer.com and shipping was fast and I will most definitely recommend them to anyone who is interested in parts.

Delivered in a timely manner. Very good product and fit.

Great for the price

  • Recommended Replacement Roof Vent Cover for Laredo 5th Wheel Trailer
    It sounds like you might be referring to a roof vent cover that goes above the roof vent fan. If that's the case then I recommend the MaxxAir Standard RV and Trailer Roof Vent Cover part # MA00-933066 which comes with hardware and everything else you need. If you prefer a different style or color you can choose one from the list below.

  • How Long Should A MaxxAir Roof Vent Cover MA00-933066 Last And What Is The Warranty
    The MaxxAir Standard Roof Vent Cover # MA00-933066 has a 6 year warranty. It is hard to give you an exact timeframe for how long it will take to become brittle, but we would hope for the cover to hold up at least through the 6 year warranty timeframe, even in the intense Colorado sunlight. Generally these vent covers will last at least that long, if not much longer. They are made of a UV resistant polyethylene, which will resist becoming brittle over time. All of that being said, sun...

  • 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...

  • Recommended Bug Screen Option For Heng's Vortex Fan Upgrade
    What you have is a Heng's Vortex Add On Fan. This fan was put in to replace the smaller Ventline fan that originally came on your camper. I recommend installing a MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 over your vent lid. This cover has a bug screen in the louvered vents that will keep insects out of your camper. It will also allow you to leave the vent lid open in the rain and when traveling with your camper. The will reduce the build up of stale humid air that...

  • Will MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 Survive Hail
    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.

  • Recommended Roof Cover For A 16" x 16" RV Roof Vent
    We do not carry vent lid covers in a 16" x 16" size but we do carry the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 which will fit over your roof vent and protect your camper from the elements. This UV-resistant cover installs over your roof vent so you can open the vent and operate the fan in any weather and while driving down the road. it comes with a removable bug screen that keeps insects out and has a sleek, aerodynamic design that reduces wind resistance.

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.

  • Screen For Keeping Out Insects Compatible with V771232-C Heng's Roof Vent
    I recommend installing a MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 on the roof of your RV as it has a bug screen built in that will keep out bugs. We currently do not have a screen that is confirmed to fit the V771232-C Heng's roof vent.

  • 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...

  • 15 x 15 RV Vent Cover Replacement Recommendation
    The closest we carry to 15" x 15" would be the MaxxAir Standard RV and Trailer Roof Vent Cover - 19" x 18-1/2" x 9-1/2" - White Item # MA00-933066. This cover goes over the vent unit completely to allow you to use the vent in any weather. The inside dimensions are 18" long x 16-1/4" wide x 9" tall so you won't have an issue putting it over your 15" x 15" vent.

  • 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...
