Everything needed to do replacement of Fantastic roof vent, one year later still holding and and not leaking. The only problem is the other vent looks old and tired compared to the new one!

Hopefully the other one will hold on strong even if it does look a little old compared to your new one, Stephen!

Everythings great except the butyl tape. It was smashed badly. I hope i have enough usable to complete the job.

Oh gosh, I hate it when it shows up like that. Was there enough usable tape for what you needed?



by:

As usual, my order arrived quickly and complete. I paid 15% more over a nationwide RV chainstore because time and time again etrailer has proved to be a better value. The Maxxfan 5100 and installation kit required only a couple of hours to install. Most of the time was spent erecting a safe support system to get on the roof of my teardrop trailer.



by:

Nozzles were damaged but I think they’ll be fine. These were a replacement for sealant tubes that were damaged/leaking.



by:

It’s been one year (1/4/23) since I purchased and installed these products on my 1994 Airstream Trailer. The complete kit was more than adequate for my job given that the trailer had a few other areas requiring attention or needing the self-leveling sealer. I waited for the ideal conditions (weather, temperature, and time of day) before applying the parts and sealing a few other external components. We’ve had several rain events and temperature swings and these products have held up very well. The trailer serves more as an office now which increases the importance for not having leaks!

This was a great choice to select these projects and particularly, from this vendor. They were very responsive and quick to get the order out.

Thanks to George and his Team!
Happy New Year 2024



by:

The original powered roof vent was destroyed by hail. The replacement unit arrived quickly and was a perfect fit. Removal of the old one wasn’t too hard, and installing the new one went smoothly. It looks and works great. etrailer is a good company to do business with. I have ordered a variety of criticsl parts from them and have been satisfied with products and service. I’ll be back after the next hail storm.

So happy to hear this, Larry! Thanks for sticking with us for so long :) Hopefully there won't be another hail storm too soon!



by:

This kit was more than adequate to do the install of the roof vent.



by:

This kit is mostly complete. The only thing missing is a guy to get up on the roof of my camper who can use a heat gun to soften all of the old sealant and yank out the old vent. Seriously, the kit has everything I’ll need to install the new vent.

Now, I can add a comment about the install materials have stood up: Very well! No leaks!



by:

I watched some videos before doing this so I was ready. The job was straightforward and materials provided worked exactly as advertised. The sealant in particular flowed right where I expected it to. Good job on this folks.

Just as always, great service from etrailer! product was packaged very well and arrived quickly! Keep up the good work!

Made the installation straight forward and easy.

Big shout out to Kimberly @ etrailer for the excellent customer service with helping me place my order. She is extremely proficient with products and guided me in the right direction to make the correct purchase item. On top of that I received the items in just 2 days! Well done.

It was easy to install and 1 year later, still no leaks.

Still great all this time later.



by:

The sealant has a bent nozzle and the tape is crushed on the sides. It may be ok.



by:

Caulk tubs arrived in good condition along with the screws... The butler tape not so much. It had no backing card so was kinda folded in half. Otherwise all is as described and arrived quickly.



by:

I bought this kit to make my roof vent install water tight. The butyl tape and self leveling sealant were exactly what was needed. The kit comes with two sets of screws (which weren’t included with the roof vent), however I didn’t use them as one set was slotted (flathead vice Phillips) and the other (better) were hex head/slotted. I prefer Robertson (square drive) screws and that is what is stock on this trailer so that’s what I used. I would have given 5 stars if the screws that came with the kit were better quality (i.e. weren’t slotted). Regardless, there is no doubt it is water tight. Good kit.



by:

I’ve yet to install it but am looking forward to using it

We're excited for you, Britten! Please let us know what you think once you get the chance to install it.



by:

Excellent service,fast delivery. My husband installed this in less than 2 hours. Everything needed is included in the kit, very good product!



by:

There's a generous amount of goo here to go with the butyl tape, maybe enough to do two hatches. My question is about the screws they send which in my case are redundant. They're all slot headed so will have to be pre drilled and installed with a standard blade manual screw drive driver ensuring a labor intensive install or removal.



by:

Always pretty satisfied with etrailer. The only reason I didn't give a 5 star this time is the butyl tape was smashed because of the way it was packed for shipping. The product otherwise arrived in good condition upon initial inspection. I haven't installed the fan yet so can't yet speak to function.



by:

The ventilation kit is okay. I ordered it along with the electric vent. Getting the kit saved me from having to go get materials.



by:

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



by:

Can't really said hadn't had good weather to install it, but shipping was quick,

Everything arrived in good condition.

  • Option to Replace Fan-Tastic Roof Vent 6500/410 With Remote
    We have spoken to Fan-Tastic Vent about this issue in the past, and they have confirmed that there are no replacement remotes available for the 6500 model as it's no longer in production. So if you want to still use your existing fan but also wanted a remote, they said what you can use is the Fan-Tastic Vent 7350 Series Upgrade Kit # FV807359. However, this is similar to getting a brand-new vent, so you can go that route, with a number of different options. For a powered lift with a remote...

  • Is Butyl Tape Needed When Installing MaxFan Roof Vent
    When installing the MaxxFan Roof Vent # MA00A04301K that you referenced you will want to use butyl tape on the vent edges in addition to the sealant that you will apply around the unit to cover up bolt holes and any other areas that might lead to a leak. I have attached a sample vent installation on a different model vent just so you can get a better idea of the process.

  • How to Determine Which Trailer Roof Vent Cover will Fit a Trailer
    In order to determine the correct roof vent, measure where the vent opens. The standard trailer roof vent opening is roughly 14-1/4" x 14-1/4" and have roof vents that measure 14" x 14". To pick the correct cover, you will also need to know the type of hinge you need. There is a 3 point hinge, such as the one on the Camco # CAM40153; a 4 point hinge as seen on the Camco # CAM40154; or a rolled metal continuous hinge like on the Ventline # BVD0449-A03; and universal hinge as shown on...

    We do have replacement vents and vent covers that you can choose from. It is most likely a 14 x 14 vent as that is the most common, but you will want to measure yours just to make sure. A great 14 x 14 option that looks clean and is functional is the Ventline Ventadome Trailer Roof Vent # V2092SP-28. It comes with a white cover and is operated manually so it is less expensive than an electronic option. I have attached a video of this vent being install on a trailer for you to check out....

  • Recommended Replacement Fans For a 2007 Fleetwood Discovery 39L Motorhome
    I recommend upgrading to the Dometic FanTastic Roof Vent # FV807350 for both your fans. These are controlled by a remote and allow the fan to either vent out or in. This would allow you to easily circulate air through your camper having one blowing air in and the other out. They can also be set to activate at a certain temperature to help keep your camper at a comfortable temperature when the AC is not needed. It also has a built in rain sensor so the lid will close should it begin to rain....

Since you are installing in a location that doesn't have power wires run, you will need to run a power wire like # 12-1-1 or # 10-1-1 (sold by the foot) to your battery or to another 12V power source that can handle that draw.

    You are right that the # MA00-06200K and the # MA00-07500K are very similar vent fans as far as most of the internal components. The main difference is that the 7500K uses a remote and has a powered lift. The 6200K is manual control and manual lift. Other than those features they are effectively the same. We get a large majority of good feedback on both models, and I would not expect any noise issues with a brand new fan. As far as the voltage regulator, we have found in most cases they...

  • Availability of Replacement RV Roof Vent Lid for 13-1/4 x 14 Roof Vent In Bigfoot Truck Camper
    I'd measure again because roof vents are 14" x 14" where they mount into the roof of a camper, so in that case you'd be good with the universal replacement lid # MA00-335002 in the smoke color. If your vent is really mounted in a 14" x 13-1/4" hole then you'll need to remove it, enlarge the hole, and install a new vent # V3092-603-00 with install kit # 344270KITW. While this is more work, there just aren't parts for any roof vent that isn't the standard 14" x 14" any more.
