  • 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.

This is a 2d attempt so, hopefully it doesn't come through twice. I purchased this to cover my hail damaged roof vent on my Cougar 5er & it works perfectly. The quality is great & the installation was simple. I'm very pleased with it & I like the fact I can keep my vent open when traveling. The only negative is, it doesn't say if it comes with mounting hardware so, I ordered some & now have an extra set of hardware.

Great. No regrets.

Best customer service ever! Product came very well packaged. Installation was a breeze - just doing a swap out for white covers. We love the sleek, all black appearance of our roof!

- MA00-933069

We've transferred these from one travel trailer to our new 5th wheel and found these covers have held up to all of our weather conditions, heavy rain, wind, snow, even hail. When I was removing them from the old trailer I thought for sure they would be brittle and faded from the sun but nope! Other than a few scratches they looked like new and this is after 4 years with them. Installation is super easy (about 10 minutes) and love being able to keep our vents open to help regulate the inside temps of the RV without worrying about rain getting in. And they look good!

- MA00-933069

Quick delivery, great instructions, quick install. Looks great and American made.

- MA00-933069

Easy install and matched dark colors on trailer. Look real sharp.

- MA00-933069

recieved this item quickley and no problems . It fits my Dexter vent on my Heartland travel trailer just like advertised .I can now open my vents with no worry at all. I am older and from time to time I tend to forget .

- MA00-933069

I am very happy with the Maxxair vevt that I ordered from you guys! Very easy installation,very durable and a nice addition to my car trailer. I highly recommend this product. Mike Kuch

- MA00-933069

Very easy to install. Great product. They work great.

- MA00-933069

Would have been excellent, but one of the two units had a small, 1/8" hole in the top where the injection molding did not break off correctly. Simply a matter of closing it up with some black silicon that I just happen to have out working on something else. Installed perfectly.

- MA00-933069

Quick delivery , easy to order. Vent covers arrived in good condition.

- MA00-933069

Great for replacing older vent covers.

I put two of these on my trailer in June before going on my first epic trip to Ohio from Florida. They look great but I am not sure what happened as I lost two screws on the trip (no jokes). I saw two lock washers and the regular washers on the screen of my vent. When I went up on the roof and found the other two screws/nuts that were still holding the cover on were loose. I checked the screws on the cover up front and they were loose as well. I am glad they did not fly off while I was driving. I replaced the nuts with lock nuts and longer screws plus put the lock washers back on as well.

They are still on and I have not had any issues with the nuts coming loose since putting on the lock nuts. I check them at least twice a year when I inspect the roof, wash and treat it. It is great when I travel as well because I open the vent and the hot air is pulled out which makes it bearable from the heat when we set up. I live in FL for yes it is hot.

Easy to install! Haven't tried it out pulling down the road yet, but will this weekend.

- MA00-933069

Easy to install and works great

- MA00-933069

Easy to install. Seem secure and look g reat.

- MA00-933069

This product has held up through a few storms and have functioned as described. Definitely a benefit to reducing some of the heat that comes into our motorhome throughout the summer.

- MA00-933069

Had this cover for a year and it is doing its job.

So far so good. Has survived the Florida hot sun

A recent hail storm broke clearance lights and the maxxair vent covers on my 5th wheel. Due to the excellent product descriptions etrailer has online I was able to order the correct replacements, this was especially true of the clearance lights. They are installed and fit perfectly. The maxxairs were originally installed mostly for hail protection for the camper vents, they worked in that regard but were ruined themselves. After more inspection the AC shroud and two more maxxairs need replacement those too I will order from etrailer.

Comes with butyl caulk which needed for the installation. No issues installing - just need a big hole saw. I bought stainless screws for the installation as I was installing in aluminum wall material.

- MA00-933069

Worked great to cover a vent on our new travel trailer. It gives extra protection and allows me to leave the inside vent open all the time. I found the best etrailer installation video online Not sure why that one is not posted on the product page.

- MA00-933069

The Max air covers are exactly what I wanted the service was prompt delivery was fast and there was no problem with installation they went on faster easier than I expected I would definitely use those again on anything else or I would refer them to any of my friends are using travel trailers or motorhomes to cover their roof fence very well made and looked really sharp to thank you for your prompt and speedy delivery on a well-deserved product.

Very easy to order what I need, thanks again for making ordering easy

- MA00-933069

Fast service, great product. The only problem was that the box was ripped apart an taped all around. ( I'm sure it was the delivery trucks problem) nothing was damaged. Thanks again for fast service and shipping

- MA00-933069

Excellent quality, replaced an old white one for my enclosed car trailer. Looks great, price great, very happy thank you! Will buy again.

- MA00-933069

The hardest part of replacing this thing was getting onto the top of the camper. 15 min job. The price was right. And after a year of sitting in the sun, it still looks and feels like new. No brittleness.
