Best RV Ventilation in 2022

Last update: January 8, 2023

Are RV vent covers necessary?

RV vent covers are designed to keep out rain, snow, and insects while allowing fresh air to enter. They are an important part of the RV and are necessary for proper ventilation. Vent covers should be checked regularly and replaced as needed to ensure that they are functioning properly.

Can you have too much airflow?

Too much airflow can cause problems with your computer. It can overheat your components and cause your system to crash. It can also cause dust and other particles to build up inside your computer, which can lead to hardware failures.

How do I increase the airflow in my RV?

If you want to increase the airflow in your RV, there are a few things you can do. First, make sure that all of your vents are open. Second, you can try using a fan to help circulate the air. Third, you can crack a window to let some fresh air in. By doing these things, you should be able to increase the airflow in your RV.

How do I keep my RV damp free in winter?

If you are RVing in an area with cold winters, you'll want to take some extra steps to make sure your RV stays damp free. Here are some tips: 1. Use a moisture absorber. This will help to keep the air inside your RV dry and free of moisture. 2. Keep the windows and doors closed as much as possible. This will help to keep out any cold, damp air. 3. Use a space heater to keep the inside of your RV warm. This will help to prevent any condensation from forming on the walls or


Camco RV Vent Insulator And Skylight Cover With Reflective Surface, Fits Standard 14" RV Vents (45192) Review:


These things satisfy my preference for items with multiple uses in a number of ways. We've already used these Sunshield Vent Insulators for a variety of purposes, making them one of my favorite recent RV equipment purchases. To start with the fundamentals, they are made of approximately 3-1/2 inch white foam rubber "They are just a little bit bigger than the typical 14" square RV roof vent opening because they are roughly 14-1/2" thick and square. If you're concerned about the scent of foam rubber, rest assured that it remains unnoticeable even after a month of use. A white fleece cover that zips off allows for washing is included with them. You simply insert them into the square vent aperture to use them in your roof vents. The foam slightly contracts to provide a friction fit that seals, insulates against heat, and filters out the majority of light. They have never fallen out while I've been towing, even on some really bumpy road sections. Simply grip the fleece cover and pull to remove them.After purchasing three of these insulators, we went on our first camping trip at a lake in Texas in late July. We noted that with the Vent Insulators installed, our air conditioner ran significantly less frequently and our coach stayed at a very comfortable 68 degrees, despite the afternoon temperatures pushing into the high 90s.The majority of the light that would typically enter via the vent covers is blocked by them. (The amount of light they block is shown in the photos.) We've discovered that's a fantastic perk for us on mornings we'd prefer to sleep past "first morning light." Additionally, we've discovered that they make excellent throw pillows and serve as seat cushions for a portable folding bench.Since these photos were taken on 8/26/16 and I bought them on 7/27/16, I've only had them for about one month of primarily hot, sunny Texas weather. If you carefully examine the image of the tape measure on the 14 "On the Vent Insulator's surface and edge, where it has been rubbed against the vent crank handle for the most of the past month, you can detect a few very small impressions. This impression gradually faded away over a period of time.On hot, sunny days, I've read that some customers may slightly crank open their roof vent cover before installing these to let some of the heat that accumulates between the insulator and the plastic vent cover out. Even though it's not a bad idea, I wouldn't open them too wide because you can end up with moist Vent Insulators if there's an unplanned downpour.



Camco 40161/40168 White Unbreakable Polycarbonate Vent Lid - Ventline (pre 2008) & Elixir (since 1994) Review:


When we discovered that our old camper covers had been damaged by a few small branches striking the roof of the camper, we bought these new Camcos. Since we installed them a few years ago, our camper has experienced hail and winds over 100 mph in Glen Arbor, Michigan. On Mackinaw Island, Michigan, at the time, I was not in my camper. When I came back, fearing the worst, I climbed on top of my 36-foot RV and saw that many of the sewer's plastic covers had been shattered, but the Camcos hadn't been (I have two openings with these on top). Then, I observed cracks in my awning and an accumulation of ice chunks adjacent to the camper. Since we still have wonderful sunlight, I'm really delighted that things are so durable. Regards, Camco



Camp'N RV Exhaust Vent Cover - RV Range Hood Vent/RV Range Hood Cover (White) Review:


Our three-year-old travel trailer's Ventline brand cover had suffered significantly from the sun, so I bought this vent cover to freshen things up. I especially wanted an icy white appearance, and that's what you get here!Although the kit includes stainless screws, I reused the white-painted screws from our camper to maintain the aesthetic. The screw holes are nicely aligned. I also enjoy how the outer edging is more rounded than the previous one. The vent's back duct tube was considerably deeper than the one I was replacing it with, but I was able to trim down just 3/4" with a set of metal snips to make it fit my caravan.I'm unable to predict how soon it will deteriorate in the California sun, but I'll return later to update this description with my observations.Although it's inexpensive, it seems just as well made as the Ventline-branded one I took off.



Camco 40148 Replacement Vent Lid for Ventline/Elixir (Smoke Tint) Review:


As others have noted, there are no instructions. I figured it out in about 10 minutes. Get on the roof and observe how your original cover is put and how it performs. Bring a helper inside to help. No component of the old or new cover should require you to be overly harsh. Uncrimp the end 1/4 while the cover is mostly lifted "tabs on the existing cover hinge, I opened these tabs with a needle tip plier. Take the 1/4" retention clip's thin end off "the J-shaped elevating arm's rivet pin. Install the clip after saving it. The flat round head can now be disengaged by flexing the bottom edge of the long slotted track. This light weight metal track has just the right amount of flex to enable this. I bent the bottom of the channel using the flat tip of a screwdriver. Slide the old cover off the hinge once the arm has been disengaged. Reengage the pin, slide the new cover onto the hinge, and crimp the ends of the new hinge. Reinstall the clip on the rivet, and you're finished. While you're up there, replace the seal around the cover opening. When ordering the cover, purchase the seal at the same time. I hope that clarifies more than it confuses. Not difficult, just difficult to convey.



Camco Replace-All Plumbing Vent Cap with Spring Attachment - Replaces Lost or Damaged RV Plumbing Vent Caps | Fits Up to 2" Plumbing Vent Pipe - White (40034) Review:


My ceiling was damaged when a roof vent made of 2" PVC pipe leaked. It turns out that it passes via an attic 90-degree elbow, and that elbow developed a leak. Snow or rain that had accumulated inside the vent leaked out the elbow and onto my ceiling. Although I replaced the damaged elbow, I installed a few devices to stop leaks in case any of my other roof vents failed in a similar way. In my opinion, both devices are extremely affordable insurance against a potential issue.The first device can be obtained on Amazon under the name "Camco 40034 Replacement Plumbing Vent Cap (Polar White)". It's a cheap and efficient technique to ensure that water never again enters my vents while yet enabling the vent to breathe for $5.18 and free shipping. The cap is highly durable and glides onto the pipe with ease, ensuring that no strong wind will blow it off. Even if it might not last as long as my 30-year-old roof, I'll just buy more when I run out.The "Oatey 14206 2-Inch Carded RC-2 Collar" is the second device, which is also available on Amazon. While checking my roof vents for various issues, I found the rubber flashing boots were deteriorating and, though they weren't currently leaking, I was concerned they would in the near future. These perform very well for $2.27 and free shipping. Simply put them over the current boot to extend its life, protect it from further fading from the sun, and provide a second seal around the vent pipe. Once more, it might not last as long as my 30-year-old roof, but I'll just buy more when I run out.Pictures of the devices installed on my roof vent are shown in the attached pre- and post-photos.



Camco Standard Roof Vent Cover, Opens for Easy Cleaning, Aerodynamic Design, Easily Mounts to RV with Included Hardware-(White) (40431) Review:


Excellent cover pricing, quick 30-minute installation, and very easy. Mark the cover holes on the roof with a pencil, place the brackets where they will be closest to the metal frame's corners, and then mark and drill four holes in the vertical metal frame of the RV. Finally, attach the brackets with the included hardware. Although you can't open your vent as much as you could without the cover, it still allows for more than enough ventilation, thus it's not really a significant concern. I've been hearing complaints about durability and sun rot shortening its useful life, so it's clear that this is not made of UV-resistant material and that living in Arizona, where the sun can quickly degrade items.I roughed up the surfaces and used high-quality spray paint to cover the attachment points and the lower 3" of the cover completely.This should create a barrier from the sun over the most vulnerable attachment sites, which are also the most vulnerable areas to break.If this straightforward remedy succeeded, I might upgrade reviews and stars in the future.



Camp'N 14" Universal RV, Trailer, Camper, Motorhome Roof Vent Cover - Vent Lid Replacement (White 2 Pack) Review:


Funny how much thicker and stronger these are compared to the originals. Both installation and assembly are simple. The originals, which were fragile and brittle, crumbled before my very eyes as we drove to Myrtle Beach. To bring it home, the remaining torn bits needed to be duct taped. There were a few videos of repairs on YouTube. Fortunately, it did not rain during the few days it took for items to arrive on Prime. It was great that they came in a two-pack because my second vent was almost as awful. I could immediately tell these covers were of a higher caliber when I initially opened the package. The originals were made of thin plastic similar to milk jug plastic. These are considerably milkier, slicker, and much thicker, like a lunch tray. Allows light to enter, yet they are opaque. They had a small amount of hardware that needed to be assembled, and it was enjoyable to do so because it was so simple. In no time, I had them prepared. I transported them to my RV storage facility, where I installed both in approximately 10 minutes. My son did the high-flying work on the roof with my assistance. The covers, a flathead screwdriver to uncrimp the "hinge" end, and a needle nose to recrimp were all he had with him. Using a cordless driver and a #2 phillips bit, I completed the interior work. Like I stated, no problem.



Camco Universal Vent Installation Kit with Putty Tape- Use to Replace or Install Roof Vents, Side Mount Vents Plumbing Stacks and Refrigerator Vents (25003) Review:


The screw holes may not match, which is a good thing, so using putty tape makes for smooth installation. After cleaning up the leftover debris from the previous fan's installation on the roof, you should place the new fan and record its location. Take the fan off, then cover the old holes with putty tape placed precisely inside your markings. Use the new screws to attach the fan. Once the new screws and edge of the fn shroud are sealed with Dicor self-leveling sealer, the installation is finished neatly.

Heng's 71111-C1G1 Standard Mount Universal Vent - White Review:


decent bargain. An excellent replacement for the old vent. A thicker roof is necessary for the installation of the bottom trim. I installed the trim that came with the vent after making a trim out of PVC board. None of the screws are included in the package, so save your old ones or buy some before you begin the installation.
