Most Popular Plastic for 2018 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.

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!

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.

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!

The 2250 Fantastic Fan still working great after a year! Pretty quiet and the thermostat is a handy feature that works well. In my application, it has a tendency to open itself while driving around unless it has been cranked down fairly hard. Driving with it open doesn't seem to be a problem other than the outside noise that comes in that way. My application was a fiberglass raised top on a Chevy van. I had to make a wood frame as the fiberglass did not provide a flat surface to mount to. Photos below show inside frame, fan, and insulation.

Excellent unit, does what we require. Replacing really original units that were installed on my old Airstream

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!

A good replacement for the original fan. I don't mind using the remote control.

No complaints. No leaks. Seem to work great.

Excellent product and easy to work with. Great service. I was concerned however about insects entering through the vents so came up with a filtration system. Used a PVC coupling and some filter material. Cut the coupling to 1/2 inch rings and remove just enough material to allow an inside press fit. Cut round filter and insert first then hold in place with the ring. On the outside vent cut a long narrow piece as shown. When installed as shown, adds very good double filter and allows air to move freely. Just finished a 6000 mile trip clear across the country and back and filter performed perfectly. Eliminating the heat build up AND keeping the bugs out. JIM : ]

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.

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.

Everything needed to do replacement of Fantastic roof vent, one year later still holding and and not leaking. The only problem is the other vent looks old and tired compared to the new one!

This powered roof vent is great! I mounted it above the cab in my 1991 high-top conversion van to provide cool air when camping in it. Fan is more powerful than I expected! I rarely need to switch it to high speed. It's quiet enough for sleeping just a few feet away. Installation was easy and dimensions were accurate. Controls are easily accessible. Auto temp control is really nice when outdoor temps are dropping during the night so we don't get too cold. Rain sensor triggers to close cover after only a few drops of rain! Reversible fan is nice.

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!

Great upgrade, moves alot of air, choice of direction. Installed in primary space - pulling air in improves effectiveness of second vent in shower.

Works great before it failed! Seems the fan is not sealed . Moisture gets on the control pad and on circuit board, poof dead. Needed new circuit board and new touch pad in less than a year . But does work well when it works

This unit fit a 2013 Keystone Raptor. It was easy to install, does not leak and works perfectly. The shipping and customer service were fast and fantastic from etrailer!

This was an easy install as it was a direct replacement.
