I think the Amazon seller has the dimensions wrong, it fits in the standard vent opening in RV's

I had thought about installing a Hengs Vortex fan but the CFM rating on them is only 188 CFM. The MaxxAir 4500K fan is rated at maximum 900 CFM, I ended up installing 2 of these. We make quite a few trips to Florida and I needed fans that were capable of moving a lot of air and I really like the thermostatically controlled Auto mode feature on the MaxxAir Units that will adjust our fan speeds according to the desired room temperature setting. Also my wife is short and the remote controls help her to not need a stool to turn on the fans.

There is a you tube video on the install that is informative.
We replaced the cheap and extremely loud fan in our bathroom with a Heng vortex fan. It took about 15 minutes to install. Very quiet. We love it.

I put 2 Fantastic fans in the GFs 5th wheel. The one in the bath is a manual opening and 3 speed. A bit noisy in higher speeds but very effective. In the living area I got a higher featured 10 speed one with a remote. It's in a tall ceiling so manual operation was impossible. At high speed it is a bit noisy but lowing speed to the 5-6 range very quiet. Both have the rain sensors which I think is important and I also put the shroud over the living area one so we could use it in rain if necessary. I have the Max air fan in the Raptor toy hauler 3 speed controlled by the "In Command" panel and not offensive in high speed.

You say you do not need a remote. For us the remote was the main reason for getting one in the bedroom. Having to climb up on the bed to turn it on and off was getting real old. Love having the remote on the wall now. I also removed the real cheapy they had above the stove and replaced it with the one removed from the bedroom.
Which ever one you buy, just make sure you take care removing the old and installing the new with the correct sealing materials.

Thanks all for great replies!! I did order the manual lift 3 speed Fantastic-Fan for the bath room as no problem reaching controls. Not really concerned about the noise of a fan in the bath. I really appreciate the insight regarding the accessibility of the vent over the bed. I would never have thought of that. Even though we've been doing in for years with our previous 5er this one is now taller (no more bent over bed making).
When you mentioned re-purposing the bedroom one for an exhaust fan for the stove did you mean mounting it vertically to replace the hood vent? If workable this has potential to be a real improvement to the very wimpy stove exhaust hood and could cut down on winter condensation during my ice fishing trips!

I guess I'm a day late. I replaced one of our Fantastic fans with a MaxxAir and it is superior in many ways. I like the digital temperature setting on it and how much quieter it is. Even the vent lid is a better design with dual lifts instead of one. When our other Fantasic goes I'm replacing it with a MaxxAir.

Update: So I ended up buying a Maxxair 4500. And it seems to be a great fan with just a few test since it's been installed. My wife being a little short was also a good reason to get the remote control. She loves it!
This one was installed in the bathroom. It was very easy to install and I think I probably had a total of two hours to do it including cleaning up afterwards.

I appreciate all the input on this. It helped a lot in the final decision and I'll probably get another one for the kitchen in a few weeks.

Thanks,

Craig

Don't know if this has been mentioned, but I'd keep the bathroom door open when running the fan at higher speeds. Replacement air has to come from somewhere, and you'd rather that that not be the black tank.

How is the fan going to pull from the black tank? If you say through the toilet you need a new seal.

Our RV's bathroom door has about a one inch opening all along the bottom so as to let the bathroom ceiling fan pull air in. This is the same as all doors in our stick house - each door bottom is about one inch above the floors so that the central HVAC system can drawn recirculating air from each room's registers back into the system's main intake in a hallway.

MaxxAir vs. Fantastic vs. ?? Which One?

Our Maxxair 7000K running at a higher speed definitely will pull stink out of the black tank for the duration the pedal is pressed, even with the door open. The fan is pretty much over the toilet, which may be the reason.

When running at 30%, the speed used for showers, it won't.

Of course it will when the hole is open but not otherwise.
