The lowly RV vent! Useful and Inexpensive
The lowly RV vent is something that can make a big difference in your RVing joy.
Or, by ignoring the vents, it could cause RVing nightmares.
I don’t know if you have noticed, but you will get a little bit hotter than you think you ought to be simply by being in an RV. Why? Because of radiated energy and also because of a small volumetric space, your own body heat and such can make an RV “stuffy” and hot.
To make your RV even better than simply having windows for a cross breeze, someone came up with the idea of a roof vent. This makes complete sense as it will allow hot air near the ceiling of the RV to escape through the the vent, drawing in more comfortable air through the windows.

But vents have many aspects and I’ll list a few in bulleted form:
- Unpowered Vents
- Powered Vents
- Roof problems with Vents

Our Experience with a Fantastic Vent – Powered RV Vent
Sheri and I had a Fantastic Vent – which was a powered vent and in my opinion it is one of the best rv vent fan you can buy. If pre-installed, just be glad you have a good one.
The powered vents are very powerful and should not be confused with the very small fans present on the RV bathroom vents. The bathroom vents must be at least 50x less capable in terms of moving large amounts of air.
We did have a problem with the switch in our Fantastic Vent needing to be “worked” up and down from the roof so that the switch started working again. The cool thing – once we figured it out, it worked great.
This particular switch turned the powered vent on and off. You would raise the weather cover for the powered vent and when the cover was open far enough the vent would turn on. This was a nice feature and example of a system to prevent turning on the vent while the weather cover was closed.
Manual RV Vent or Unpowered Vent Info
The most common vent is a simple RV vent that is unpowered. While the powered ones are incredible, not having a vent at all would be terrible in an RV.
Why? RV’s suffer a more from heat due to the added effect of radiated heat inside the RV, in addition to thin walls and reduced insulation. Most regular buildings have thicker insulation and walls and can knock down the radiated heat much better.
Therefore, since the insides of the RV can get super heated, it is really important to give the hot air a chance to escape and pull in cooler (relative of course) air from the outside.
These unpowered RV Vents are actually very good at doing just that.
I know that when I open our vent, even though it is unpowered, I can definitely feel the hot air escape and the room then get some instant temperature relief.
We always make sure to check the vents throughout the day when we are coming and going – not because they are unreliable, but because we use them and they are very easy to forget to close when rain or other inclimate weather comes along.

I am trying to figure out how to clean my roof vents without getting upon the roof. They are full of bugs and dust webs. I live in my 3rd wheel and am 71 and can’t get up on the roof. Can I use my hair dryer to blow the junk out ? Thanks for any info.

You know I’ve never done that. My first inclination would be to take out the screen from the inside. I think many vents allow this. The for the ones that won’t, I’d hire a kid for $10 to climb up and clean it out.
