Most Popular 4-1/8 Inch for 2016 Ram ProMaster 3500

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.

I am happy with this fan in my Ford Transit Connect. It is a standard height SWB Transit so I didn't feel I needed a more powerful fan. I like the built in light. I need this to fit in my garage so this fit the bill for a reasonable price. I will be running it off a portable power station and solar to charge the power bank. My van already had a popup vent installed so this should move some air through nicely. The installation after watching a few videos went smooth and took a few hours. I cut the roof hole, put down butyl tape and self leveling lap sealant. My roof is thinner so I did not need to use the middle extension piece. I did use my own 1" self taping screws. I would say I have moderate skills with tools and measuring. My electrical skills are minimal but I did not have any issues with this. Just put it in this morning so I haven't camped with it yet.
