Best Ram ProMaster 1500 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.

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!

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.

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.

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.

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.

Great instructions. Very nice product. Installed nicely and looks beautiful. You will need to buy the butyl tape to properly install and of course the self leveling roof sealant.

This vent fan helps a lot with keeping my 7x14 cargo trailer cool. Did a lot of modifications with my trailer especially insulating the ceiling and now with this fan makes it better and cooler. The lid is always open to let the heat out because i have the MaxxAir II cover so rain cant get in. Fan runs better with more or bigger airflow from the side vents when all doors are closed so i added the Redline II popup vent and it works great. Fan does not slow down. Im glad i got this and will be purchasing again when i get another trailer. Thanks ETrailer

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.

I received the product today. Customer service to this point has been excellent. It will be about a week before trailer repair folks will be here to install, however, I did open and inspect the product. It was not protected in the box and is wedged into the box. I pray it will not be damaged.

Operates as described but when closed lifts slightly (flutters) in windy conditions. I’m concerned it might leak when it rains but haven’t been in those conditions yet.

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 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.

Valterra Battery Box Cone Vent and Louvered Cover - White Cone with White Cover - A10-3300-05 Replacement vent for 98 5th wheel. Great fit, does the job, but the Louvered cover could be better quality, does the job, but could look more impressive. Plus you will need to supply your own screws and material to install them.

Direct replacement for the vents on my 5th wheel.Look great

Great product, exactly what I was looking for. My roof tox box for windsurfing equipment was getting far too hot inside living on Maui. I placed 10 of the vents around the box by drilling a 2 1/2 inch hole and glewing the vents from the inside. This way I only have a clean hole showing from the outside and installation is very easy. Box is around 30 degreees F cooler now and air circultaion also takes care of the moisture.

Worked well installed 4 vents to Rubbermaid 68-litre tote used to store my 30-Amp Hughes Autoformer rectifier in line to my Lance RV Travel Trailer

Several of the vent covers were crushed in shipping from being stacked in the boxes (metal arm from one on top pushed in to one under it). Trailer promptly replaced them after sending pictures. A testament to their customer service and satisfaction. I would definitely order from them again. The covers themselves fit perfectly on our 2017 Montana 5th wheel

Perfect replacement for our 1999 Jayco Kiwi bathroom vent cover. Easy swap out. We are ready for another year of outdoor enjoyment thanks to etrailer's excellent customer service.

Seems to work well. I didn't end up using the included putty. There was so much lap sealant around the old hole I couldn't remove it - was 3mm thick and I was afraid of tearing the roof membrane. So I leveled the old lap sealant with a razor blade and then screwed right through that to install the new vent. Fresh lap sealant around the edge and over the installation screws and tada

This vent works just fine. However, I also purchased a set of 16 inch G rated tires to replace the E's that came on the trailer. Best decision I have made regarding the trailer. We own a 40ft Grand Junction with a 14,000lb GWR. Have been Cal to Florida with no problems and good wear. Even across the desert at 114 degrees we just cruised. Looking forward to my next trip where I no longer worry about the tires blowing.

Fast shipping and knowledgeable. I used these items as vents for battery boxes.

Just what I was looking for. Looks to be a very well made. Was priced well. I have not installed it yet.

Excellent, powerful fan & my second Maxx Fan purchase in total. Consistently great products. Shipping box was damaged & there were some smudges on the top of the fan, but... it's not like anyone is going to be looking at the top of it anyway & nothing inside was damaged, so all's well that ends well. Definitely a fan of the white top over the more popular "smoke" color for a smidge less heat absorbtion. Also glad that the manual fans continue to be offered as the remote-capable alternatives hardly seem worth the upcharge in situations where the fan is within reach.

After many months of fretting over cutting into the roof of my new van, and waiting for the rainy season to end, I found the installation very easy, and the operation is great. We're currently on a road trip, and the MaxxAir has made camping much more comfortable, and it even improves air circulation while driving with the vent open. it's very quiet at low speed and no leaks in even the heaviest rain.

I installed this as a bathroom fan through the sidewall of my T@B teardrop camper. Works great.

Product is fine will update once installed. etrailer yall got yo do something about your terrible shipping. I mean order on 7th of March delivered by Pony Express on the 15th. Yall got to do better. Not ordering again unless they ship thru someone other than USPS! Slowest Shipping on internet!

Great product, we use these in all of our trailers.

Excellent product, we have been installing these in our trailers for years. We have found etrailer to be quick to ship, and reliable in their products.
