It came with easy instructions and all the parts rare these days . Thank you for a great price and quality . I will be shopping with you again or sure .And couldn't believe the emails checking to make sure everything was ok .

My local dealer wanted 225.00 installed for one of these. I bought mine from etrailer and saved big $$$. Was so easy to install, my wife actually said she wanted to try to do it so I sent her up on the roof and she had it installed within 30 mins, (would have been 15 mins but she didn't push it far enough forward the first time and the vent cover wouldn't open fully) . Overall I would highly recommend this product

Fast delivery, great product, fair pricing. Really like the fact that you can remove the screen and clean out debris that has fallen on top of the vent screen. Covers fit perfectly over the vent lid, secured down with the attached hardware that's included. Heavy duty design; had to replace other covers that got cracked bad due to hailstorm. Will always purchase from etrailer.com; they have the right products for use.

Excellent great quality product!

It's fine. It's as good as it gets. Two very smart things: 1. This manufacturer supplies aluminum mount brackets and stainless steal hardware, so nothing will rust. 2. I also like the removable filter grill. Just remove the two SS screws at the top and it rotates easily right out into your hand. Clean the filter as needed, slip it right back into place and reinstall the screws and go pop yourself a cold one.

Can't say enough good praises for the help Andrea gave me on helping to find replacement lids for the vents on my 1985 Wilderness travel trailer. They fit perfect and the added Camco roof vents are a plus. No more leaking should I forget to close the vents. I would buy from etrailer.com in a heart beat, S&H was excellent and the personal help from the staff is superb!!!! Thanks Again!

Exact replacement for my old weather/sun deteriorated vent. Very good instructions helped with smooth installation. When used with Camco cover, can use my trailer as dry, vented storage or to actually tow something somewhere, with no adjustments needed for venting.

Still very happy with the Camco roof vent. Works great on trips and I keep it open when using trailer for motorcycle storage in my driveway - still no leaks!

These have proven to be a great product. We are putting these on all or trailer roof vents and have seen a dramatic decrease in loss of vents due to blowing off when left up.

My camping trailer is 7 years old and one of the roof vent covers was falling into pieces. It seemed strange since it was made for outdoor use. It was easy to find a replacement on etrailer.com and it arrived promptly. I installed is easily using the existing hardware on my trailer. No more than 5 minutes later the new cover was installed. Customer service order status and tracking is great.

The Roof Vent was easy to install. It fits well and should really help vent the various oil & gas fumes from the trailer. Instructions are clear and installation took under 30 minutes.

Just as described in video. Appear to be of excellent quality. I have several trailers, wish I knew this product-junction box- was available years ago! Can't wait to get started on the project. The Camco vent covers are the same as in retail stores, but at a savings from etrailer. Although I have installed others on RVs I have owned, your instructional videos are a good review.

Ordered 3 of these covers and they are fantastic. Put them on the day before a very heavy storm and had vents open and not a drop of rain came in and keep the trailer a nice temp. WishIgot them before. Easy to install make sure drill bit is sharp as hard to get holes made.

Ask the Experts about this Camco RV Vents and Fans

  • Need a Roof Vent Cover For Fan-Tastic Fan
    I suggest the Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover - 23" x 19.5" x 10.25", # FVU1500WH. This is designed to fit all Fan-Tastic Vent trailer roof vents. It is common for the vent lid to make some contact with covers however, the # FVU1500WH, will open most of the way and allow 100% of air flow produced by the fan. There is the option of the MaxxAir FanMate RV and Trailer Roof Vent Cover - 25" x 18-1/8" x 10-1/4", # MA00-955001 which is a little taller.

  • Can You Install an RV Roof Vent Rain Cover on A Plastic Roof Vent?
    You are correct, most older roof vents and/or fans do have a galvanized steel roof flange that mounts to the top of the RV. The Camco Roof Vent Cover, # CAM40431, that you mentioned is often used with these style vents/fans as seen in our installation video. In recent years, many manufacturers have begun to use roof flanges made from sturdy plastic, including our friends at MaxxAir. I called my contact at MaxxAir to ask about drilling into the plastic flange. He assured me that their...

  • Roof Vent Cover Recommendation that Allows Vent Cover Lid to be Fully Opened When Needed
    The Camco RV and Enclosed Trailer Roof Vent Cover w/ Detachable Louvered Screen # CAM40431 that you referenced is designed for a 14 inch by 14 inch roof vent to fit under it. When installed the vent cover will only be able to open at about a 45 degree angle. Which under normal circumstances would be just fine. A better solution for you would be the part # CAM40431. This cover will allow a roof vent to be open at all times without letting water get in.

It measures 18-1/2 long x 18 wide x 9-1/2 inches high, so it will install over the top of your Ventline dome vent. I've attached some videos to help.

  • Will Camco Enclosed Trailer Roof Vent Cover Fit Over MaxAir Vent On Casita Travel Trailer

  • Is There Gap When Installing Camco RV and Enclosed Trailer Roof Vent Cover?
    There is a very small gap between your roof and the Camco RV and Enclosed Trailer Roof Vent Cover # CAM40431 though this should NOT be sealed. This gap will help stop condensation from forming and the installation of this is leak-proof so that is not something that you are going to have to worry about.

  • Recommending a Vent and Screen For Van

The Camco RV and Enclosed Trailer Roof Vent Cover with Detachable Louvered Screen, # CAM40431, will keep the moisture out while sitting atop the Ventline Ventadome Trailer Roof Vent, # V2092SP-28, which has a screen to stave off whatever bugs may try to squirm their way in.

If you are looking for a rain cover compatible with this vent, I recommend the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066.

  • Vent Cover for Use with Ventline Vanair Trailer Roof Vent VP-543SP
    When your trailer is moving down the road it is best to have all fan-powered vents closed. Apart from the rain concern the impact of wind at highway speeds might put excessive stress on the vent and/or its lid. You definitely do not want to operate the vent's fan motor while the trailer is moving as it is possible that the motor could be damaged by the force of air interfering with the fan blade's motion. We do offer covers for vents, such as those like # CAM40431 and the others displayed...

  • Recommended Vent Cover To Mitigate Water Leaks In Vents
    Extremely heavy winds can cause leaks around the vent, but this is incredibly rare. Normally a leak will be from a crack in a lid that needs replaced.

  • Can Ventline Vanair Roof Vent with Fan be Used in Van
    You can definitely use the Ventline Vanair Trailer Roof Vent w/ 12V Fan # VP-543SP in your small van on the weekends. It moves 100 cubic feet per minute so one should be enough to stop condensation for a couple people. It isn't going to make things noticeably cooler though because it is a vent and fan as opposed to something that supplies cold air - it will really just circulate the air. As for the rain, I recommend leaving the fan closed because it is possible some water could get through...

  • 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 Camco RV and Enclosed Trailer Roof Vent Cover w/ Detachable Louvered Screen # CAM40431 will fit a Ventline E-Z Lift Ventadome Trailer Roof Vent # V3092-603-00. I do have to mention that the # V3092-603-00 will be 9 1/2 tall, and the # CAM40431 is also 9 1/2 inches tall, so there will be some contact when opened all the way. However, this will not affect or damage either product.
