Most Popular Roof Vent for 2021 Ram ProMaster 2500

Bought two for my Promaster camper conversion and they work great

Great fan, I am extremely happy with the quality of the product and glad I chose etrailer for my purchase. I installed in a 2015 Promaster myself with no problems. After you get past the anxiety of cutting a hole in your roof, it goes smoothly.

Best RV fan design on the market delivered without issues. This is the second one I am adding to my Promaster van build. It will go in an aluminum panel that will replace one of the rear door windows. The two fans will afford flow through ventilation soas to minimize the need to run the rooftop ac unit.

I really love this MaxxFan Deluxe. It runs really nice and really helps regulation the temperature in my Tradrop trailer. Only minor problem is that the tip of the rotor shaft sometimes rubs against the screen, squeeking a bit. Would be nice to have to have a means of holding the screen down so that it does not rub. I have not needed to use the remote so could go with the next lower model without the remote. But overall this is a great fan!

This fan is a great innovation because one can leave the exhaust port open without fear of rain. This prevents the buildup of humidity when your unit is parked. The fan itself is powerful and effectively draws air through our travel trailer.

This was my first purchase from etrailer and I was blown away with their customer service and incredibly fast and accurate delivery of my order! Thank you etrailer, I’ll certainly be back for more great service!

Fan installation is very straightforward. Perfect fit and looks and works great. Hardest part was removing old caulk - plastic scraper and patience worked well for me.JUST TAKE YOUR TIME.

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

My Maxxair fan was easy to purchase on etrailer.com. The shipping package came early and in excellent condition. Packaging was superior. I will be using the fan with my Promaster van build. I have purchased from etrailer before and will again as the need arises. My experience with etrailer is exceptional. I recommend them highly.

Very nice addition to my Seismic. Should have came already with the trailer since the trailer is $$$$$. The remote is crazy BIG and its wall mount cradle is not design for RV use. Leave the remote in the wall mount cradle while in transport will soon produce a ejected/broken remote :(

Works as advertised. Quiet at slower speeds, a bit noisier at higher. No rain leakage from cover. Was a bit hard to clean fan blade after some months of use as I didn't have a hex key to fit the set screw. Wish I'd got the remote control version, but was trying to keep things simple. For my Promaster install I got a custom plastic gasket online that made for a very tight seal with roof with minimum silicone gunk everywhere.

The MaxxFan Deluxe Roof Fan works great with good airflow and is very quiet in comparison to the vent/fan it replaced. I will likely replace the non-fan equipped vents on my RV with the same MaxxFan.

Fast shipping, good price!

Just installed, so no use experience yet. Need to add rear overhang dimensions to the specs. I hesitated to order because I couldn't confirm that it would clear my shower skylight, but it did fit!

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.

Product is very cheaply built and flimsy. It has a small cheap fan blade that moves very little air. Choose a different brand

Great fan with multiple speeds, including reverse. Easy to install, comes with everything you need (except butyl tape). Has made a really big difference in the temp. comfort in my RV. The only negative is the supplied electrical connectors-I put them on, tested the fan & then installed the trim ring- then no fan! Turn out the connectors had fallen off- replaced with standard wire nuts and reinstalled the trim ring....VOILA....coolness!

I've had the fan in for a season, and a couple southern road trips. Generally happy. It will run "all night" with no problems on the stock dual batteries in my Ford Transit passenger van. Didn't spring for the remote and maybe would the next time. the controls are bit small, hard to reach, a touch confusing for groggy, middle of the night changes. Fan is quiet and efficient but even on high, directly over the bed, it's not going to bath you with sweat drying air movement. Quality seems good, I installed with an aftermarket, designed for the transit roof profile, ring, it went well. I painted the interior trim with gray "for plastic" rattle can paint to match the Transit ceiling and that is good stuff, it held up well to multiple on offs while getting the install just right". I also brush painted elastomeric white roof coating over the exterior caulk and and mounting screws, zero leaks so far.

It does what it is supposed to. Works great. Just used to replace old vent in horse trailer.

Have also purchase this vent before. Found it to be of good quality and fit for the trailer. Will continue to use E-Trailer for my trailer needs.

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.

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.

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

Install very easy I am going to use it to exhaust hot air when camping and I have a portable air conditioner in the van the hose will go right out the vent size 2 purposes

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.

It's a good product but it has a flaw. I installed one on my van less than 2 years ago. The fan motor quit. I couldn't find a replacement motor on MaxxFans site so I bought this entire new unit. The motor is tiny and cheap.

Love the light...installed myself. Not the easiest install but well worth the effort. Would not hesitate to do again.

Works great! It's in the ceiling of our shower. It moves the moist air up and outside. The light in it gives us a well lit shower. Our shower is 36x36. We are satisfied. We recommend it!

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.

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

Product arrived on time and in good condition. Installation was pretty straightforward….and everything works! A great addition for my truck camper shell!

Quite, good air flow and it was easy To Install.

I bought this vent to fill the hole left after the AC delete on my old RPOD. I'm not noticing a lot of air movement, as this is a non-powered / no fan vent. But most importantly.. I'm not getting any water coming in and I no longer have about 100 pounds of useless AC creating drag when I tow.

Installed on my Ford E350 Super Duty Van. Always nice & cool in the rear section now compared to the last vent I had up there. Great quality item! etrailer is great to deal with. Been using their items for years.

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

Etrailer helped direct me to the MaxxFan 7500 I believe letting me know that I can probably use the wires to a near by light to power it and they went extra and sent me to videos and also a way to still use the light to with a special switch. I realized that the bathroom fan wasn't working too and an older dome fan so ordered this right away as it's replacement. It arrived in manufactures box and all parts appear to be with it. I also have the sealant materials so it's ready to be installed as soon as our weather up here in NW MT cooperates. Great extra mile answering my questions about installing an electric fan into a screen vent no power space but same size. So helpful to know it's possible.

Great communication, exactly what I ordered!
