Best Mercedes-Benz Sprinter RV Vents and Fans

Bought this to replace original bath fan (Maxxair) when the raising mechanism broke. I ordered it from etrailer on a Wednesday, and it was delivered on Friday....super fast delivery. Easy install, and I think we will really like it's features (i.e. 10 speed reversible fan, rain proof cover).

I purchased 2 of these fans to replace the old fan in our RV. Absolutely love these fans and the features; keeps out the rain open or closed, auto on at set temperature, in or out air flow, remote control, low profile design, and straight forward installation. If you are considering a fan replacement, I highly recommend this fan.

Nothing but issues. It has worked fully for maybe 3 months in the last two years. At multiple times an owner of these will experience the beeping and blinking green light issue. You’ll be told “oh, moisture in the mother board” so, you replace the PC board and add electrical waterproofing (which voids your warranty). That holds for a while then the beeping and blinking starts again “oh, its gotta be the current draw, the fans require a solid 12v”. Add a DC/DC stabilizer to each fan should settle the issue. Nope, only another two month fix. You can reset these fans easily by just disconnecting the power to them and that seems to get some time but the issue of your fan not going above low and the beeping and green light will inevitably return. there seems to be a lot of people who experience this exact issue leading me to believe it’s a quality control issue at and is not being addressed. I would not recommend these fans to anyone.

It worked great until it didn’t. I used the fan approximately two dozen times over the course of a year. I usually ran the fan for an hour or less. Now the fan controls just beep. It will not turn on.

This Exceeded our expectations; we didn't know that this would have such an impact on how much air was moved by this vent fan. I was in, then out of the "Doghouse" for the cost of this (the wife did her own research after I had) and then the wait; the unit this replaced was leaking water as it rained outside. Within a week of ordering this it was delivered, and the following day I got it installed. Installation directions were very simple to understand/follow; the hard part was removing the old vent fan and caulk. Another "Bonus" was how quite this is compared to the original.

When they work, they do really well. Mine started squeaking loudly, so it has been returned. The designers of this model were kind enough to install a super bright green LED that shines when in auto mode, which is where most people will use it. You cannot shut off the LED unless you take it out of auto mode. If you like waking up to a green light, as in an alien spacecraft coming to pick you up for a free ride, then this is the fan for you. Otherwise, shop around because that light is really really bright! If it wasn't for the beacon that you cannot shut off, this would be a five-star review of a fan.

Fan arrived quickly and was an exact replacement for our Hail storm damaged unit. Thanks eTrailer!

Our hunt club has 2 pit blinds that are used for waterfowl hunting. Each blind is essentially a concrete box with walls, floor and top 4 inches thick and dimensions of 12'x5'x5'. Each blind is buried to a depth of 5 foot to where the top is flush with ground level. Access is through the top using 24 inch wide manhole lids that are made of high density plastic. The cooler air inside of the blinds clashing with warmer air absorbed by the concrete and manhole lids at ground level caused condensation that made the inside damp and smelly. We only hunt 3 months each year, so needed a vent solution for the other 9 months the blinds were not in use. We also needed something that could be powered by DC voltage from a solar panel due to the remote location. In July 2015 we installed each fan into a manhole cover and used water-tight conduit and electrical boxes to run the wiring from the solar panel to each fan. Great solution! Once enough daylight hits the solar panel the fan blades start moving and run constantly until sundown. Will see how long these things last but so far so good

Installed this fan myself, fairly easy to install, once you fix the stuff that they should have cleaned-up and finished at the factory. Fan works as expected. MUCH better than the cheap fan I got at purchase. Happy with purchase, would buy this fan again.

Installed this product in my camper roof a year ago now. It runs and functions as advertised. I would recommend it to anyone with the same item replacement.

This vent was bought to replace one of the roof vents on my recently purchased used horse trailer. The top section of the existing vent was completely missing so rain could come right on in. It was easy enough to remove the damaged vent. Took a bit of elbow grease to remove the old sealant off the roof. The new vent is EXACTLY the size needed and installing it took less than an hour. Now the vent is fully functional once again and no more rain coming straight into the trailer either!

I really like this product and will purchase the second one. It basically solves the dust problem in our canopy, as it pressurizes the canopy and keeps the dust out. Great product and recommend buying it.

I have two of these installed in our stepvan - they were one of the first things we installed during the build process, and thank goodness we did because they kept us cooler during the summer build. Easy to use, the multiple-fan settings are nice, and the exhaust feature can pull a lot of air. We don't have AC, so these fans make a huge difference in pulling out hot air and replacing with outside air. Great service from etrailer - I ordered the wrong fan the first time and they were great to work with in getting another shipped out to me.

These are awesome! They can be used whether it is raining or not, no middle of the night scramble to shut all the vents. Since install we rarely run the AC. We have 2 installed, with a 3rd vent being the brand "fantastic fan" (it was our 1st one installed). Wish we would have known about these before listening to the dealer and wasting our time and money on the 1st install--all would be the MaxxFan Deluxe Roof Vent!

Delivered as promised in fine shape. MaxxFan fit perfectly in existing 14X14 opening. Simple install and is functioning as designed.

right out of the box I replaced everything and it will only work on high. something is defective. customer service was great but won't work on low or medium.

I cannot recommend this product. It came with a crack in the fan blade assembly that results in severe vibration and noise when running. Neither Dometic nor Etrailer have been any help in providing a resolution. I can't even purchase the part I need without buying a full motor assembly, which I don't need, and which is going to cost $70. See pics. I have video as well but the page won't allow me to upload.

Perfect roof vent fan that should have been installed from the factory. Pulls plenty of air without a lot of noise with minimal battery draw. We use this when we shower, or as a fan to pull cool air in at night when sleeping. Good build quality.

Fan arrived on schedule. Installation was a simple replacement of my second Dometic NOT SO fantastic fan. I should have purchased a MaxxAir fan two years ago instead of wasting money on a Dometic. Once all the old caulk was removed, this fan slid right in and was connected to power within a minute. Operating this fan via its remote is pure pleasure (the dometic's remote was very frustrating), with its LED screen confirming mode, speed, temp, and fan direction. All of this with a minimum number of buttons and clean layout. I did reuse the interior cover from my removed Dometic as its was the same size, trimmed to fit, and the screw holes would have been exposed if I used the MaxxAir cover which has rounded corners (both are white). I previously ignored all the recommendations to purchase a MaxxAir, and I paid the price (money and very bad performance). Don't waste your money on other brands, buy a MaxxAir MaxxFan.

We love this fan! The remote is nice for me as I can't reach the fan. Nice to be able to reverse airflow, too.

This item was not package well at all scratched up the top of it and was bent on the corner, put it out in the sun to straighten it up. Unfortunately the order took 13 working days to arrive it sat in the UPS warehouse for 8 days claimed they did have enough drivers, I had to talk to them and etrailer folks sever times to get the shipment delivered, I guess when you live 100 miles from the warehouse they will take there time. On a side note there was a cargo slide and 3 other items on this shipment. not very happy with T-Force I think etrailer should look for a different delivery service Other than that it worked fine. The only reason for 3 star is packaging and shipping when you pay $XX for a plastic item is should be wrapped up in bubble wrap a least it was stuffed in a box, nothing else in it. Wow.

The motor is noisy. When I try to contact the company there was no reply. I have the same fan in the RV already this was an addition to replace a non fan vent so I know how it should sound. I will buy a new motor for it and see if there is any reason to buy the product again. I waited months to receive the fan so it was disappointing the finally receive it and get it installed only to have it noisy.

Vents work great for the year that I have had them. I got the aluminum version to reduce any chance of rusting. I just painted the vents and they were just fine. Been going solid for a while now. The vents are a bit flimsy for the mechanism but I just baby it and it has been fine.

Nice product. Received this morning, installed by 2PM. Painted it to match the color of my truck. Easy to install; used the garnish as a template. Fixed the vent with stainless screws and the garnish with finishing screws. Had to trim down the garnish height by 3/4 inch which was easy. The vent is to be used either as a snorkel to get positive air pressure in truck cap, keeping road dust away, or as a normal vent.

They are great I use on my snowmobile trailer.canleave the vent open all the time.

Pretty easy install. It works great to let in fresh air without the rain and snow.

The ventline roof vert is just a little better than having nothing. I installed it to fill the hole where a RV roof air conditioner was. The fan motor is very weak and does not move hardly any air. Also the plastic cover that cranks up is very light and is not heavy enough. It vibrates awful going down the highway. It is very annoying. No way does it compare to a fantastic fan that are in RVs. But it did fill the hole from the air conditioner.

The item arrived damaged. No damage done to box so it should have been caught before shipment. Need to return for replacement.

Fit the old opening just fine. Easy install, I had to install backwards because of the roof slope on my A-Frame trailer.

This vent is well made and assembly was very easy. Installed with a liberal bead of flex seal caulk and flex seal aerosol as final sealant.

Installed this vent into my Haulmark Transport 6'x12' enclosed trailer. Installation was easy, I cut a 14.25" x 14.25" inch hole between two crossmembers in the roof and dropped it in place. Because the roof on this enclosed trailer is so thin, I used a piece of 3/8" plywood so sandwich between the interior garnish and actual vent. I cut the same size hole into the plywood and left a 2" lip all around. I use 28 #8 x 5/8" stainless screws to hold it in place, pre-drilled with 1/8" bit. I then used roofing tar to seal the vent and put masking tape all around, leave 1" from the flange to ensure good coverage. I then removed the masking tape, leaving nice clean lines. Interior garnish is held in place by #8 x 3/8" galvanized screws. Huge kudos to etrailer for carrying such awesome products for great low prices and offering super cheap shipping to Canada!

My truck build; I have developed, invented, a new kind of truck cap and also wanted to provide the best venting in the industry and this is why I wanted this product. Although it is a little flimsy it is easy to install and easy to use. And it adapts well for my use. My product (I hope to have available in good stores like Etrailer by years end) is a rigid, folding, adjustable (fits most trucks), one person on & off, and easy to store when off pick up truck cap or camper. See attached photos of my prototype build. Many have inquired to use it for their pets, for camping, and many other uses.

The vents were exactly what I needed to vent the kitchen of my home-built teardrop camper.

RV storage compartment. Design of RV led to condensation in compartment and continual mold issue. This vent fixed the problem. It might require a slight modification to accommodate your situation.

A great solution to increase the air flow in my UTV. 2024 RZR. I removed the screen to increase more air flow. I think this increases air flow twice as much. Easy install!!!!! I placed it on the roof.

Installed on a SxS utv roof for ventilation on warmer days. It gives a much more comfortable ride. Very glad I took the time to install it.

Well made vent should last years. I like the removable screen for easy cleaning. Unfortunately the roof vent mounting flange is badly damaged. I will need to do some work with my hammer and anvil to make it useable. This is clearly incorrect/damaged.

I’m very pleased with the quality of the vent and how easy it is to open and close. This was a replacement for the previous vent that became inoperable and leaked.

The caps that I received were original replacement caps. Installation was fast with only two screws on each cap. Vents were close to the edge of the roof of my Airstream so I could replace them from the ladder. I was done in less than 30 minutes. The customer service was terrific and I got the caps in two days. With the new caps and gaskets, I am hopeful that our bathroom and shower will be drip-free.

James was great to work with over the phone. He knew his stuff and very nice to work with. He assisted me in making sure that the roof vent cover was the correct fit (and it was). It was an easy install and will keep the rain out during our wet Northwest winter.
