I like it a lot,I think it’s the perfect upgrade for my Chevy express van. Will post pics,once its on. Thank you.

I am happy with this fan in my Ford Transit Connect. It is a standard height SWB Transit so I didn't feel I needed a more powerful fan. I like the built in light. I need this to fit in my garage so this fit the bill for a reasonable price. I will be running it off a portable power station and solar to charge the power bank. My van already had a popup vent installed so this should move some air through nicely. The installation after watching a few videos went smooth and took a few hours. I cut the roof hole, put down butyl tape and self leveling lap sealant. My roof is thinner so I did not need to use the middle extension piece. I did use my own 1" self taping screws. I would say I have moderate skills with tools and measuring. My electrical skills are minimal but I did not have any issues with this. Just put it in this morning so I haven't camped with it yet.

Easy to install. Has worked daily for the last year. Does not provide nearly the air flow of larger versions, but helps keep the stale air out. Excellent customer service from etrailer.

This vent works great as my bathroom also has a window so I really didn’t need a regular vent that opens. I couldn’t be happier with it. The LED light is a nice touch.

The package was delivered on time and looks great! It was missing 2 screws but otherwise its great. Also would be a good idea to send the required butyl tape and a small tube of caulking to make it a complete kit.

Review from a similar Mini in RV Vents and Fans


So far so good. It lets very little light through from outside, in the main living space I would like this, as I have kids who are still at the napping age. in the bathroom I don’t like it so much. Other than that it appears to be well made. Installation was a pain, but no fault of this unit. The old butyl tape was a lot of work to get off the roof.

Review from a similar Mini in RV Vents and Fans


I purchased from etrailer a Maxxair Mini RV Vent and Fan and after owning it for a year I’m still pleased with the reliability and quality of the system. The installation was so easy that even I could do it! My wife and I camp with the kids, their friends and other family members, so the fan gets a work out to say the least! I have already recommended etrailer and Maxxair to other campers so if you are asking me then go for it! I have experience with etrailer and their customer service is on point.


Comments
This fan is still working great and the surrounding light kit is futuristic. My old fan kit was dated so my wife was pleased to see the update! Thank you for the opportunity to offer my feedback and if it ever wears out I will surely be back!!!

Very windy here right now so have not started install. Appears that the vent is going to be tight in the opening. The old top was torn off in the last wind even though it was closed at the time & the r v was parked. Will see how it goes tomorrow morning.

Fan works okay but light ring quit working. Tried to repair the tiny wire that broke but couldn't. This is actually the second unit I've owned on which exactly the same thing happened.

Review from a similar Mini in RV Vents and Fans


Final result is nice. I'm really pleased with the low profile on the roof. It's kind of a hassle to install. They should rethink the piece that connects the roof section to the ceiling section. Make it telescope so you don't have to cut it.

Review from a similar Mini in RV Vents and Fans


I used this vet to replace the crank up vent in my bathroom. I was a bit disappointed that it doesn't let in as much natural light and the vent I was replacing, but with the build in LEDs the lack of light was manageable. However the plastic cover isn't quite strong enough to hold up to Texas hail storms and I found broken louvers and a large crack in the vent cover after one bad storm. It isn't leaking (yet) but when it does and I have to replace it I'm not sure I'll install another one of these.

Ask the Experts about this Maxxair RV Vents and Fans

  • Does the MaxxAir Mini Deluxe Trailer Roof Vent MA00-03851 Have A Wall Switch
    If you need a powered roof vent fan that has a control panel that you can mount on the wall then I recommend using the Ventline Ventadome Roof Vent w/12V Fan and Wall Switch part # V2119-3-533. The controls for the MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 are on the unit itself and there is not a wall mount for this fan so I don't think it would be a good option for what you are looking for but the above will do what you need. The Ventline Ventadome has a 12 volt fan, powered...

  • Solution for MaxxAir MaxxFan that Clicks and Fan Won't Shut Off
    Sounds like your roof vent lid isn't closing all the way when you ask it to which is why the fan isn't shutting off and also explains the clicking of the operator as it's trying to close it. In the past we've seen similar issues to this turn out to be fixed by replacing the operator with the part # MA10-20281K-1AF which is correct operator for your MaxxAir MaxxFan.

  • Side Wall Mount of MaxxAir Mini Deluxe Trailer Roof Vent
    The MaxxAir Mini Deluxe Trailer Roof Vent, # MA00-03851 was not designed for side mounting. You can of course attempt to but I suggest you first consider the MaxxFan Dome Plus Roof Vent, # MA00-03810B as this product was designed for either rooftop or sidewall installation. This is designed to fit roof or walls from 1" up to 6" and is more compact than MaxxAir Mini Deluxe Trailer Roof Vent, # MA00-03851.

  • Could MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 be Used in Bathroom
    There's no reason you couldn't use the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 as a bathroom fan. It's an exhaust fan that would do an excellent job in this application. I attached a review video for more info on this for you to check out as well.

  • How Low Does the MaxxAir Mini Deluxe Trailer Roof Vent Sit Below the Ceiling
    The MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 once installed will sit almost flush with the ceiling. The panel which houses the light and control knob I would say is around 1/4" - 1/2" thick so that is all that would sit inside the trailer. I have attached a photo for reference.

  • MaxxAir Mini Deluxe Roof Vent # MA00-03851 The Lights Won't Turn On
    I have found in some cases when installing new vents with lights like your MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - Black Item # MA00-03851. In order for the light to work a wall switch must be turned on.

  • Can MaxxAir Mini Deluxe Trailer Roof Vent be Powered by Wiring to Bathroom Light Switch
    The light switch in your bathroom should be connected to 12V power but I'm not sure that's where I'd connect the power for the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851. Reason being that if you wanted to leave the fan on but turn the light off then you wouldn't be able to do that. Since this vent fan has it's own on/off switch I'd try to locate another 12V power source or connect this to the light circuit before the switch so that your light and fan can be operated...

  • Does the Trim Piece On the MaxxAir Mini Deluxe Trailer Roof Vent Need Trimmed for Installation
    In regards to installing a roof vent like the MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851, the white trim piece that connects the top and bottom of the vent is called the garnish and this will be trimmed to fit the exact thickness of your roof. The provided garnish works with roofs 1" to 4-1/2" thick but there are taller ones available if you needed.

  • Exterior Height of MaxxAir Mini Deluxe Trailer Roof Vent with Fan
    The black top of the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 is just under 4 inches tall so with the white base and black top combined, it will sit about 4-1/8 inches above the roof. I've attached a video to help with some of the other components, but have attached a photo for reference to the measurement you requested.

  • Can MaxxAir Mini Deluxe Trailer Roof Vent Fit on Box Truck
    The MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03851 (Black) and # MA00-03801 (White) will fit on your box truck's roof if the roof is between 1" to 4-1/2" thick and has a standard 14" x 14" opening. In regards to weight, these vents are 7 lbs. Additionally, if it is less than 1" thick would be able to use some plywood to increase the thickness to install the vent. I have added links to video reviews of both.

    The MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Black # MA00-03851 and the MaxxAir Mini Deluxe - White # MA00-03801 that you referenced are indeed identical units except for their lid color. Both are 12V DC powered exhaust fans with 1 speed option and feature an integrated rain shield to prevent water from entering the RV or trailer. Any difference in price between the two options is simply related to manufacturer pricing and supply and demand. I have attached a video demonstration...

  • Do I Have To Reseal My Roof When Using the MaxxAir In Place Of a Fan-Tastic Vent Roof Vent
    The MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 will fit the same size opening as the Fan-Tastic Vent Roof Vent that you have now but you will need to use the included garnish that is supplied with the unit that way everything lines up properly. Therefore, you will need to do a bit of weatherproofing but this is really easy and all you will need is some silicone sealant like part # 0160297.

  • Will MaxxAir Mini Deluxe Vent Fan Offer Quieter Operation Than Ventline Fan
    We have found that the MaxxAir vent fan assemblies tend to be just a tad bit quieter than the Ventline alternatives, although in all honestly they're very similar. I wasn't able to track down a specific decibel level for the MaxxAir Mini Deluxe # MA00-03851 that you're considering, but based on customer reviews I think it is going to be quieter than your existing Ventline # VP-543SP. Multiple customers have written back about the the MaxxAir Mini Deluxe models praising its quiet performance,...

  • Could MaxxAir Mini and Deluxe Roof Vent Be Used in Bathroom Application
    There's no reason you couldn't use the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 as a bathroom fan. It's an exhaust fan that would do an excellent job in this application. If you'd rather use the larger in size MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-05301K you certainly could as well. The fan moves quite a bit more air and is reversible too which you might find helpful.

    The MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 is not compatible with the remote on the similar model that does not have the light. As long as your current fan is one of the MaxxFan Plus: 00-04500K, 00-04700K, 00-04800K, 00-04900K or MaxxFan Deluxe: 00-0700K, 00-07500K, 00-08500K, 00-08700K, 00-08900K models then the circuit board you are looking for is the Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan # MA10A21275K.

  • RV Roof Vent Recommendation
    The smallest roof vents we carry are 14" x 14" in size. If you are willing to alter the cutout hole to fit that then I recommend the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - Black Item # MA00-03851. It has a vent cover that will allow the vent to be open in all weather and will protect against bugs and debris. It also comes with LED lights and the exhaust fan is quiet and energy efficient.

  • Recommended Vent Fan for Cargo Van with Reversible Motor
    In order for a vent fan to have both an intake and exhaust feature it will need to have a reversible motor. The MaxxAir Mini Deluxe Trailer Roof Vents like part # MA00-03801 for white or part # MA00-03851 for black don't have reversible motors. Instead, I recommend the Fan-Tastic Vent Roof Vent part # FV801250. In regards to installation which will apply to pretty much all roof vents, the roof thickness will need to be at least an 1".

    The MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03801 for white or part # MA00-03851 for black is a single speed fan yes. However, when the light is on the power to the fan is reduced so you will get sort of a low speed setting but it's not exactly controllable outside of this instance.

If you're looking for something with a powered vent lift, the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - Black # MA00-03851 is a great option.

  • Replacement Motor for Ventline V2265 Vent Fan with Plug-In Port
    Since your Ventline V2265 model fan assembly features the plug-in port for the motor, the correct replacement is indeed the part # BCD0390-00. This is a direct replacement and it will plug right in just like your existing unit. Unfortunately we don't currently have a replacement fan blade that will fit your existing Ventline model. If a new blade is needed your only option will be to replace the entire unit with a current model, such as the MaxxAir Mini Deluxe # MA00-03851.

  • Recommended Fans for Use In Horse Trailer
    I do have an option for you but the only solar powered fan we offer is the Ultra-Fab Solar-Powered Plumbing Vent part # UF53-945001 and this would not move much air in your horse trailer. The same can be said for most solar powered fans of its kind as they are really not designed to move large quantities of air. Therefore, a much better option for you would be to install a few 12 volt powered vent fans. I recommend the MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 or part # MA00-03801...

You can add this using installation kit # 344270KITW.
