Most Popular Reversible Fan 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.

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 :(

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.

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.

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
