Most Popular Powered Lift 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.

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 :(

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.

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.
