Most Popular 5 Inch for 2017 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.

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!
