Roof vent install kit allows you to properly mount your RV roof vent and create a waterproof seal. Kit includes 2 tubes of self-leveling sealant, 1 roll of butyl tape, 8 wood screws, and 30 sheet metal screws.


I assumed this installation kit would be packaged separately from the roof vent, but instead all that stuff was just thrown in the box with vent. There was sealant that leaked on screen for the vent. Poor packaging job.


Product came in very quickly and seems to be in great condition. Will be installing the fans in a few days but looks like it is straight forward. I would like to thank Jesse M for the great customer service.


Screws were a combination of screw types and none were self-tapping. Otherwise had what I needed.


The installation kit contained everything I needed to install my new roof vent. I only used about half of the tape and less than a full tube of sealant. Happy trails!


Provided everything needed for a successful install for the roof vent I purchased from you.


Great service and pricing. I really like that they help include whats needed to install the parts your buying


As described, on time delivery. Great products and service.


Your website is difficult for me to navigate. For instance, I type in trailer windows and there are 50 plus pages of things that have nothing to do with windows. Without question you guys have lots of products, just hard to find.
Thanks, Mark


Screws were a bit shorter than I thought they should have been.


Always nice dealing with etrailer. The customer service is second to none.


It was easy to install. The hardest part of installation was removing the screws from the old vent.


Product came quickly
Instructions were
Very happy with competed project


Its Great brand I had in my intech explore. I've had it for a year now in my 2021 winnebago and unfortunately the bearing is somewhat noisy. Definitely dont think it's going to hold up boondocking. Maybe theres a difference from the white unit I have now than the black that was in my intech explore.


All good stuff, Butyl tape came a bit deformed, but not damaged and can still be used


More than enough tape and caulking to install two 14" x 14" roof vents. Worked well.


Great Product and fast shipping. Thanks


Have not installed it yet just got it today but the quick response on how Fast got here was great thank you


Nice person and took care of me.


Perfect except I ordered 3 to put in 3 roof vents, used less than 1 roll of the putty tape and 1 1/2 tubes of silicone. Should have bought 1 and picked up extra screws for other 2.

Vents are still leak proof
Randy S - 06/19/2021


Ordered the Vent Installation kit, as well as the vent, to install on an older 6x12 enclosed cargo trailer. The kit is exactly what is needed for a waterproof, clean installation. Butyl tape between the vent bracket and the trailer, then self-leveling sealant over the screws and the perimeter of the bracket-trailer seam. Screws to mount the vent and the decorative trim were also included. I made due with one tube of caulk, but can understand some installs would need two. Same with the butyl tape - used less than 1/2.

Of note - first set of butyl tape arrived having been mangled in shipping. were great about immediately sending out a replacement, no questions asked. Great service

A year later, trailer still dry inside!!

Good replacement. Has held up well. Replaced on a metal roof and original was riveted down so a little harder to install, but doable.


Worked as expected, enough left over to use for a second fan installation.


Great service & great products! Thanks


The sealant is difficult to apply smooth and straight but that should be expected with this type of joint design. The etrailer videos helped with the process. The trick is to carefully apply the sealant where it is needed and do minimal tooling to smooth and fill gaps. No product data sheet is apparently available to understand how to work with the sealant or to provide preparation recommendations, cure times, and safety considerations. No success with locating the product data on the internet or the manufacturer's site. The butyl tape should be shipped flat or attached to a flat sheet of cardboard. When I opened the box it was molded into to a taco shape and had to be set out overnight to creep back into a flat roll. I did not use the carbon steel self tapping screws.

No problems with the installed products.

Received my Maxx Fan and roof vent kit on Monday 6/17/19 right on time and everything was their and in good condition. I installed the Maxx Fan on my 2017 GMC cargo van the same day, took me a little longer than I thought it would but not bad for a 74 year old guy. I watched the videos that etrailer had on their site and some other [videos] and that really helped for a first time doing this type of install. I had the wiring ready to go and the fan worked great, thanks etrailer for the fast service and a great price on the Maxx Fan.

The Maxx Fan are great, I have two of them that I installed on my camper van because I have no extra windows to open for air. They are both wired up to a house battery that charges from the vans alternator as I drive or can be charged with a battery charger. E Trailer has great videos on installs of a lot of their products and are a great help. Love my Maxx Fans and would install them again.

  • Where to Apply Caulk When Installing Trailer Roof Vent
    You would want to run a bead of the sealant around the vent opening on the underside of the mounting flange as shown in red on the photo I edited for you. Put the vent into place, pressing firmly so that the sealer spreads to the area around the mounting holes so that they are sealed when the vent is screwed into place.

  • Ceiling Garnish Installation Kit for Ventline Ventadome Trailer Roof Vents
    The ceiling garnash won't include screws but there is an installation kit for trailer roof vents. The kit # 344270KITW includes sealant, Butyl tape, and all screws needed for installation. The sealant can be painted 72 hours after setup. The types of screws included are sheet metal screws (30 count) and round-head wood screws (8 count). Garnishes are only available in white.

  • Roof Vent for a 1968 Streamline Travel Trailer
    We have several vents that might work for your Streamline trailer but nothing that is made specifically for it. I have included a link to the right to the options for you. Most of the vents require a 14-1/4 inch square opening to install the vent. The majority of the vents have plastic lids with a few exceptions that have metal lids. Beyond that it is just a matter of the color you want: white, blue, smoke, silver, clear, and metal. I also recommend the vent installation kit # 344270KITW.

  • Is There Corrosion Concerns When Adding a Ventline Trailer Roof Vent with Galvanized Steel Flange
    There is always a possibility of corrosion when using different metals. What I recommend is the installation kit # 344270KITW as it will have the sealant and screws to install your roof vent with a waterproof seal. You can always paint the sealant after 72 hours if you would like. I included a video review for you too.

  • Longer Screws For Installing An RV Air Conditioner On A Thicker Roof
    If the 8, #8 x 3/4" screws in the Roof Vent Installation Kit # 344270KITW are too short, you can use the RV Kappet Screws with Covers # 37220415 instead. These screws are #8 x 1" and include white screw head caps if you choose to use them. You don't want the screws to be too long, you'll want the screw to be long enough to reach into the structural material under the trailer roof.

  • Install Kit Recommendation for the Fan-Tastic Vent Roof Vent w/ 12V Fan # FV801250

  • Roof Vent Install Kit Recommendation for RV with Fiberglass Roof
    Since you have a fiberglass roof the RV roof vent install kit you'd want is the part # 344270KITW. The Butyl tape kit you mentioned # CAM25013 is for use with rubber roofs or sidewalls so it would not work for you.

  • Can the Fan-Tastic Vent Roof Vent Install in a 13 Inch Long x 13 Inch Wide Opening
    In order to install the Fan-Tastic Vent Roof Vent on your trailer you would need to take either a sawzall or pair of tin snips and trim the roof to have a 14" long x 14" wide opening as that is what is required for the Fan-Tastic Vent Roof Vent part # FV802250. It comes with a garnish for a watertight fit but you will also want to use the Installation Kit part # 344270KITW. The 13" long x 13" wide opening you have now is not very common so I do believe that trimming the space will be worth...

  • Troubleshooting Separated Siding at the Joints of the Trailer
    The Camco RV Vinyl Trim Insert # CAM25262 will replace your trim and allow you to have a nice molding. It is not intended to seal your walls, but to simply give you the finished look. This trim is intended to slide into existing metal track that is holding the siding in place. Since your aluminum sides are separating, I recommend using the Installation Kit with Screws and Sealant # 344270KITW to seal the siding from water and also secure it in place with the screws. I recommend removing...

  • How Does Exterior RV Shower Box Install on RV
    The Exterior RV Shower Box # 324-000061 that you referenced has 10 small bolt holes that are around the perimeter of the mounting bracket which most will use wood screws with. You'll want to cut the opening needed in the siding of your camper, then use some 2 inch by 2 inch boards to create a frame just behind the opening so that you can drill through the siding into wood to secure the shower in place. You'll also want to use butyl tape to seal the enclosure to the siding. For that we...

  • Install/Sealant Kit to Use When Installing Fan-Tastic Roof Vent # FV800900
    You will need to use a sealant when you install the Fan-Tastic roof vent part # FV800900 that you referenced. For that we have the Roof Vent Install Kit part # 344270KITW which comes with all of the sealants you would need plus screws to attach the vent. I attached an install video that uses this kit on a similar roof vent for you to check out as well.

  • RV Roof Vent to Replace Existing AC Unit
    Most RV air conditioners use a standard 14-1/4 x 14-1/4 inch opening, which is what the Camco # CAM40480 is compatible with. You can easily confirm that this is the case with your existing unit by removing the air handler or grating and measuring the rough opening through the roof. I'd also recommend an install kit like part # 344270KITW. I've linked to an article that explains how to install a roof vent.

  • Replacement Vent For Northern Breeze Trailer Vent V2525-01-S46-M
    I do have an option for you but you have a Northern Breeze Trailer Roof Vent part # V2525-01-S46-M and the replacement lid part # BVB0568-01 which has been discontinued. I was not able to find that particular lid anywhere else either. I recommend to replace the entire roof vent with Fan-Tastic Vent Roof Vent w/ 12V Fan - Reversible part # FV801250 which will fit the same cut out as your old Ventline Northern Breeze. I recommend to just replace it with a modern version because it is really...

  • Drill or Clamp Fan-Tastic Roof Vent for RV and Tip for Cutting Garnish to Length
    I like the more permanent drill application Fan-Tastic roof vents like the # FV801350 you referenced as they are easier to keep sealed. For an install kit the # 344270KITW would work well. This comes with the needed screws and all of the sealant you'd need. To trim the garnish I would recommend using masking tape to mark where you want it cut and then use a fine tooth saw to make the cut. Since it's plastic it will cut very easily.

  • Replacement Motor for Fan-Tastic Vent Fan 6600R
    I do have an option for you but there are no longer any replacement parts available for the Fan-Tastic Vent Fan 6600R due to its age. Therefore, your only option is to replace this for which I recommend the Fan-Tastic Vent Roof Vent part # FV802250. This unit has a 12 volt powered fan with variable speeds and a manual lift lid. I also recommend using part # 344270KITW for easy installation.

  • Can Existing Holes from Old Vent Assembly be Used for Hardware to Install Fan-Tastic Roof Vent
    As long as the holes where the existing screws are at are in good shape and they aren't too big for the recommended #8 screws that come in the installation kit # 344270KITW there should be no problem in using the same holes to install the Fan-Tastic Vent Roof Vent # FV801208.

  • Can Fan-Tastic Vent Roof Vent w/ 12V Fan FV807350 Be Installed In RV Roof That Is Sloped?
    As long as the slope you mention in your RV's roof is a flat slope and not a dome, you can absolutely install the Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote - Powered Lift - 14-1/4" x 14-1/4" # FV807350 and will have no issues. I do recommend using the Roof Vent Install Kit # 344270KITW to make sure you have no leaks after installing the new vent. I included videos of the products mentioned for you to take a look at.

    I reached out to Dometic with your information and they instructed me that they no longer have a replacement for your current switch. To retain a wall mounted thermostat you can switch to the Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote # FV807350. This fan uses a wireless remote that you can mount to the wall where your current switch is. The fan has 13 speeds that are automatically adjusted as needed for your temperature setting.

  • Can The Camco RV and Enclosed Trailer Roof Vent Cover Be Installed Off-Centered
    Installing the Camco RV and Enclosed Trailer Roof Vent Cover w/ Detachable Louvered Screen # CAM40453 a little bit off center shouldn't be a problem since the shape of the cover doesn't taper down too much on the sides. You'll still want to have the cover facing the correct direction though. A lot of RV vent covers with this design don't allow the factory vent cover to fully open any way so you will have no issues with it not fully opening if it ends up touching the cover due to it being...
