I love my "Endless Breeze" 12V fan:

I bought mine last August at Camping World in Roanoke, Virginia, as I
was passing by.  It'll sit in the side window with the stove closed:

I added a velcro strap to the handle, so it'll hang in the pop-top window:

It stores conveniently in the cabinet where my fridge used to be!  I
added a velcro strap to the power cord so it wraps up neatly.

It has three speed settings.  The company's web site says it draws
1.2-2.6 amps, so you may not want to run it all night on high without
shore power:

It worked well for me in the deep south summer, hot and high
humidity, sleeping upstairs with the fan on low.

I urge you not to watch this bizarre and creepy promotional video:

Apparently it was designed for cooling show dogs in their "crates" (kennels).
