Most Popular 4-1/2 Inch for 2022 Ram ProMaster 2500

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

Vent was easy to install, really didn't need the instructions. I would have appreciated a template for the hole though. That way I can just throw the template up and cut along it. A recommendation to reinforce the underside with something (I used 2x2s) might be helpful as well. You do say to align it with a joist, but who's really going to have multiple joists within 14 1/2" from each other? Otherwise, it looks great. I figured you have multiple images of the vent itself so I figured an image of how I reinforced it would be the most helpful for future installers. Thank you. Aaron

Product material and build is solid. Easy to install. I like the smoke colored cover, lets in the right amount of sun (we dry camp in the Southwest a lot). The fit between screen and frame with the open/close knob was off by about 1/4 inch in depth. Was able to adjust the knob mounting position down so as to insure a tight fit between screen and beauty ring. We have an eighteen-year-old rig, so it is challenging to find replacement parts that fit as original. But it fits great now! great web site - easy to drill down to appropriate parts. Thanks again.
