RV or Trailer Roof Vent - Manual 14" x 14"

I installed two Maxx fans in my rig three years ago in the winter of 2017. I live in my rig, and have spent most of my time in hot places like Florida and New Mexico during the summer, so I basically ran those fans constantly for three years. They did an excellent job, but like anything mechanical, they have a point of failure. It turns out that that point is at about 1000 days of constant use for a Maxx fan. The first one died on me last fall, the second one kicked out a few months later, in early December.I replaced the first one with a new Maxx fan, the 7500K Deluxe with Remote. I got it on Amazon for $230. It's a great fan. It's quiet, it draws a lot of air through the rig. I always run it on exhaust, and the specs say it pulls 900 cubic feet per minute at full speed. Seeing as I have only about 1000 cubit feet in my rig, that means that that one fan replaces the air in my rig roughly once in a minute. Two fans running at full speed create a wonderful vacuum pulling air like Charybdis sucks sea water.When I had both of my older Maxx fans drawing air, I'd close everything up except one or two strategic windows, and would get a pretty powerful breeze through the limited openings, currents of cool fresh air equivalent to the force of a fan. Very nice on hot days when coupled with a couple actual floor fans. When boondocking without shore power, it makes for a nice substitute for air conditioning.An air conditioner can pull over 30 amps, two Maxx ceiling fans and one or two high powered shop blower floor fans draw maybe at worst 2 amps, max. You can run several fans for 24 hours and use fewer amp hours than an air conditioner might pull in one hour.When my second fan died, I went shopping. The Maxx 7500 here on Amazon was running at $380 - way too much. I saw this, and the good reviews convinced me to give it a try. About a third of the price, this. Nice.I just installed it today. It's not bad. It has three exhaust settings, and two intake speeds. They claim it pulls at high speed 950, at medium speed 650, and at low speed 470 cubic feet per minute. About the same as the Maxx, but this has a dial setting, where the Maxx has has a push button spectrum to increase or decrease speed with more nuance. One major drawback over the Maxx is that on high exhaust speed this fan makes more noise. Maybe twice as much. Not so much to be really annoying, but more than I like. The medium and low settings are *much* quieter, completely acceptable.There's no remote with this new fan, which for me is not a problem, because I never use the Maxx fan's remote anyway. I'm 6' 2" and the fan controls are roughly 7' off the floor, which is no problem for me to reach. But the person I had giving me a hand with the installation is 5' 6" and she can't reach the dial.. So be aware of that potential problem.There is also no moisture sensor on this, and the lid is opened and shut manually. This is potentially problematic, because rain could be dangerous to the fan.. If you aren't on top of things, paying attention and closing the lid when it rains, water could get in the rig, or even destroy the fan. The upside is that there is no motor or sensor to break down on you. My second Maxx fan's lid motor started to fritz out on me at the very end, making an annoying clicking sound when it operated.I'm probably going to attach the Maxx vent hood that I had on the old fan, to keep the rain out. There are no hood attachment points on this like there were on my last Maxx (the more expensive Maxx fans are designed with clip points to attach lids, or like my new 7500 have a rain guard grill already installed), but I'm going to jerry rig a solution to securely attach and repurpose the old Maxx hood.The lid on this is tinted, but not as dark as the Maxx fan smoke lid. It lets in quite a bit of light, which is very nice.. Covering it with an external lid will eliminate that light, which is sub optimal.. But preventing any rain from getting on the fan or in the rig is a more important priority.Over all I'm pretty pleased. This fan in tandem with my second Maxx are pulling air like champs. On the medium exhaust setting it's pretty quiet, and is pulling plenty of air. You could get a Maxx for about another hundred bucks. It might be worth it, if you're going to use your fan constantly like I do, or need a remote to properly operate it. Paying for the extra amenities and marginally higher quality might make sense..I don't regret getting this. If anything unpleasant happens in the future however, causing me to revise that assessment, I'll be sure to let you all know.---Further Comment, 06/07/2021The fan is performing very well. I'm pleased. I've decided that I don't need any external hood on this. When the lid is completely down the fan will not run. If you pop the lid to the point the fan runs and no higher, which is not all that much, maybe a half inch or so, rain will not get under it. Opening it much higher might not be wise, if you aren't paying attention to the weather, remembering to close it before precipitation.. But there's no need to open it higher, because you'll get full drag at minimum.. I recommend doing as I do; run slightly cracked, very mildly crazed.

This new vent was easy to install. Looks so much better then the old one. It works perfectly. Good price for what seems like a sturdy vent.

This vent is very good quality for the money. The handle and crank assembly feel much sturdier than the others I’ve installed (many) and the overall quality is very good. The installation is very easy, and it fit exactly as it should. The only issue I have is that the inner portion (the trim for the inside of whatever you install this on) is unusually shallow, so look out and make sure you measure the thickness of the panel it’s going on, or it may not reach the exterior part. P.s. it doesn’t rattle at high speeds, and is nice and diffused but still lets in a good amount of light when open or closed.

So far so good. Easy installing. Had to buy tape to seal but no issues. Only had half of the screws needed but used the old ones and no issues. Wanted to reuse my old trim on the inside which green to match the interior but it did not line up. The white looks nice but can tell it's not original. Not a big deal. So far works good. Thank you.

The fan itself comes well packaged with all the hardware needed for install as well as instructions for anyone who uses them. The fan quality seems nice, it is a platic base and surround but its good thick plastic. Its almost silent and moves quite a bit of air considering. The rain sensor does work, I tested it with a drop of water. The only spot for improvement to me would be the remote. It does work but its not very attractive and feels cheap with a not very well adhering sheet plastic face. I wanted to stick it to the wall but its kinda ugly, so I set it in my rv control panel cabinet. Over all very happy with this fan at a fraction of name brand competitors.

Easy to install

Don"t buy this junk . It broke on my first trip .Vent cover flew open while driving . I had to go up on the roof of my RV and tape the cover down . Upon inspection I found the cross bar broken and the cranking mechanism mounting broken . It's past the return date so I'm #$@&*# . Now I'm out cost for covers , I bought two , the sealing silicone and my labor . Giving even 1 star would be generous .

Good but too small for my rv
