Looking for ideas for a fan installation inside the coach

Looking to see what folks are doing to cool the coach with a fan.  Recommendations on which fan to get and where to mount it are appreciated.

 

These are the 3 that I'm considering (not in any preference order):

Not considering roof mounted fans like Fantastic-fan or MaxxAir at this time.  The vent corners in my Warrior are more rounded, which will require cutting out the roof to install a roof mounted fan that is more square.

Making round corners square is easy, making square corners round is a PIA

These are what I use. The first is a truck defrost fan. These don't oscillate but they move a lot of air. They need to be mounted on something solid.

This the other one I use. It moves a whole lot of air (3 speeds). Put a waterproof 12v outlet outside so that the fan can be use outside.

Thank you.  Do you by any chance still have the spec sheet that came with the chrome defrost fan?  Looking for cfm and power consumption info.

The one I used is a Winnebago part. The PN is 122856-01-01A. The only rating I could find is 1.6 and .9 amps... 2800 & 1800 RPM

You would be surprised how much air a 5" computer fan will move with very little noise!

For a spendy alternative, check out the Hella Marine 2 speed 12vdc fan. 6.5 watts.
