LED Lighting

LED Lighting

Whether you're hitting the restroom in the middle of the night, walking into the kitchen for a midnight snack, or just wanting to add a little flare to your roof vent, this LED light is the perfect night light or accent light for your RV's bathroom or kitchen. Pop it on any time with or without the fan running.


Rain Shield with Angled Louvers

Rain Shield and Louvers

Open and run your RV roof vent any time and in any weather. This one-of-a-kind rain shield fully surrounds and encloses the vent opening, so you never have to worry about pesky rainwater seeping in and damaging the interior of your RV. Its integrated angled louvers let odors, stale air, and moisture escape while allowing rainwater to run off. This solid design saves you time and money since there's no need to purchase and install a separate vent cover.


Not only does this roof vent defeat rainwater, but it protects against bugs and debris too. The vent has 2 different screens to ensure the inside of your RV is free of mosquitos and flies or remnants of leaves and loose bark from fallen tree branches. One screen is located behind the angled louvers and the other on the exterior vent opening - both remove easily for cleaning and maintenance.

Delivery was great as always. Install very easy to my ambulance/camper conversion. It was my first ceiling vent and later found I underestimated the air flow I would want in the box. Since then I have removed this to move it to the shower/bathroom where it will work best for this application. Purchased the MaxxFan Plus w/ 12V Fan, Thermostat, and Remote - Powered Lift - 10 Speed(MA00-04500K) and FanMate.



by:

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.



by:

This product was easy to install and does exactly what I need from it. The LED light and fan combo is perfect and I highly recommend this product. Thumbs up!!



by:

I love this Maxxair fan. It looks nice, clean lines, low profile and super easy to install with thorough step by step instructions.



by:

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.



by:

LED lights started flickering then went completely out after about 10 months. Good news is Maxxair made it right and sent a replacement free of charge.
It is a quiet and powerful fan. Hope the lights last in the new one.



by:

Disappointed in the lack of speed control and the light is very bright with on dimmer. No natural light is visible when open. Would not purchase this fan again.



by:

Installed new vents. No issues so far.



by:

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.



by:

Very poor quality. In less than 6 months, the control knob had fallen off. Another couple of months & the switch no longer works at all. Don’t waste your money!

Fans have been working good. The light on one fan stopped working recently however. I’ll probably upgrade to the bigger max fan size to move more air. I give them a 7 out of 10



by:

fantastic service as allways



by:

Great fan , the most I love about it, it's has less moving par.. example the first one that I had the top would go up and down has you use it, at a years the mechanical part broke off and I am out of $170, now with this maxx air mini fan all the moving part are from inside plus there is no hatch going up and down and the inside moving part of the maxx air are only the switches/controls.. I had replace the front of my van and now I am about to reorder another one for the back since that one broke off too and the maxx air it's seem more durable pastic... Thanks maxx air.... love



by:

It works great . Much better than the fan that came with the rv new



by:

Great fan. Wish my Tab 400 came with this from the factory.



by:

Excellent customer service! Excellent p roduct.



by:

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.

The lights stopped working the second week of use. Im not so happy with the vent

I will have our customer service team reach out to you.



by:

Item arrived in good shape and looks like a quality product. Not installed yet, will add more later.



by:

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.



by:

Directions are fantastic and easy to understand. Install was a breeze.



by:

Looks and works really well really like LED light works awesome for where I put vent
Only issue I have is not with product is that it took almost two weeks to get from date I ordered it



by:

Items ordered arrived on time and in perfect condition. Can't use any of them till the snow melts. All I can say is that etrailer service is fantastic.

  • Can the MaxxFan Mini Plus Manual RV Roof Vent be Mounted on Trailer Side Wall
    The MaxxFan Mini Plus Manual RV Roof Vent part # MA00-03851 is too large and heavy to be mounted on the side wall of a trailer. Instead, I recommend using the MaxxFan Dome Plus Roof Vent part # MA00-03810B which although is not technically supposed to be mounted on the side of a trailer either, we have seen many instances of this without issue and it will be much better suited for this than the above due to the smaller size and water resistance.

  • MaxxAir Mini Deluxe Roof Vent # MA00-03851 The Lights Wont 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.

  • How is MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan Powered
    You will need a 12 volt power supply from a battery in order to install the MaxxAir vent you asked about, which is the following part number: - MaxxAir Mini Deluxe Trailer Roof Vent with 12V Fan # MA00-03851 This vent is a simple 2-wire design with a white ground wire and black power wire that connects to your RV's 12V power supply. It does come with the mounting screws so the only other thing you will need is sealant, the TremPro 644 Silicone Sealant # 0160297.

  • Can The MaxxFan Deluxe Roof Vent Be Used In A Bathroom Application?
    I went ahead and checked out the MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-05301K, and it turns out that you can use this in a bathroom application, however you are going to want to make sure that you aren't putting this above any tubs, showers or range cooking surfaces and the moisture/heat would be too high for the unit. If you'd rather use a smaller roof vent fan, you also could use the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03851.

  • 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,...

  • Recommended Low-Profile RV Roof Vent For A Trailer
    The MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03851 or # MA00-03801 for white is going to sit the lowest to your trailer's roof at 4-1/8" in height when installed. These vents come with a Rain Shield cover which will allow you to use them no matter the weather and also while driving, unlike other models. The LED light ring gives you a convenient night light or accent light as well. I've attached a video below where I'll walk you through the installation process of these vents.

  • Recommended Powered RV Vent For A 2013 Heartland Trail Runner With A 7-1/2 Thick Roof
    Technically you could use the Ventline Ventadome Trailer Roof Vent w/ 12V Fan # V2094SP-30 or the # V2094SP-28 but the garnish wouldn't be long enough to accommodate the depth of your ceiling. The largest garnish we carry for Ventline fans is # VA0445-37 at 5-5/16" so you'd have a gap between the vent and the garnish. You'd honestly be better off with the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan - LED Light - Black # MA00-03851 or # MA00-03801 for white cover. These two vents...

  • Does the MaxxAir Mini Deluxe Trailer Roof Vent Have a High/Low Fan Speed Setting
    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.

  • MaxxAir MaxxFan Will Not Stop Or Close Without Pulling Fuse
    I contacted MaxxFan and according to them you have a bad circuit board. Circuit boards are model specific so you will need to purchase the correct board for your model. This means you will have to look at your fan to find the model number and identify which model you have in order to choose the correct replacement part. The Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan # MA10A21275K is compatible with the following models: MaxxFan Plus: 00-04500K,...

  • Difference Between MaxxAir Mini Deluxe Roof Vents # MA00-03851 and # MA00-03801
    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...

  • Replacement RV Bathroom Fan Vent
    The only round ceiling vent we have is actually made to fit the standard vent hole that is square. It is the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan in white # MA00-03801 or black # MA00-03851. We do not carry anything that is like the residential round bathroom fan.

  • Can The MaxxAir Maxxfan Deluxe Be Mounted Backwards On A Trailer
    Per the manufacturer, the MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-07500K can only be placed with the louvers (back opening portion) facing the rear of the trailer. Any damage to the vent caused by it being incorrectly installed would void the manufacturer warranty. I actually ran into this a couple weeks ago doing an install. I got the old roof vent off and grabbed the # MA00-07500K to put up in the opening and the cover was 2" too long and came into contact with another cover on the...

  • Mounting Orientation of MaxxFan Deluxe Roof Vent # MA00-07500K
    While the MaxxFan Deluxe Roof Vent # MA00-07500K can be installed in an alternate orientation from its intended design and still function. My concern is positioning of the vent grille, it needs to be positioned in a way that ensures rain won't be allowed to enter. Alternate installation will void the warranty. But yes, it can be installed vertically and still function.

  • 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.

  • 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.

  • Recommended Replacement Roof Vents For A 1999 National Sea Breeze Class A Motorhome
    For the vents there are quite a few options so it really just depends on what features you'd prefer to have. My personal favorites are the MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-07500K and the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03851 for when there isn't enough room on the roof for the curved lid of the Deluxe. Both of these vents have a lid that allows them to function during inclement weather and while driving, unlike most other roof vents. I've seen too many...

  • CFM Rating for MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03851
    The CFM rating for the fan in the MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03851 that you referenced is 200. 200 CFM is a decent amount that would also be on the quieter side as well.

  • MaxxFan RV Roof Vent that Has Remote
    We have a similar RV roof vent that comes with a remote but the # MA00-03851 that you referenced does not come with a remote. Instead you'd want the part # MA00-07500K that does have this feature as well as a 10 speed fan instead of a single speed fan.

  • 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...

  • 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.

We do have another option that comes with a rain shield so you can use the vent in any weather and also while driving with the MaxxAir Mini Manual RV Roof...

    For your application I have a few options depending on what exactly you're looking to get out of a roof vent. For a basic roof vent that will just help keep heat from really building up in your car hauler trailer I recommend the MaxxAir Mini Manual RV Roof Vent # MA00-03700 because it has a manual lift and is covered so it requires no electricity and you can keep it open all the time - even when you're driving or it's raining outside. For a mid-tier option I recommend the MaxxFan Mini...

  • Replacement Circuit Board for MaxxFan Roof Vent w/ 12V Fan
    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.

  • Recommended RV Roof Vent For An Enclosed Trailer Hauling Paint
    The MaxxFan Mini Plus Manual RV Roof Vent # MA00-03851 would be a great option if you're trying to use the fan while on the road or in inclement weather, but it doesn't have a thermostat so you would have to manually turn it on or off. This option doesn't require the lid to be lifted open like most RV vents. If you're wanting a vent that can automatically turn on when temperatures get too high and would still have a weatherproof lid then you'll want MaxxAir's Deluxe line. There are manual...
