First cool weather trip in my new (to me) pop up

Jeff,
We always found the bunk end fans noisy and mostly useless for moving air. I just got the most quiet small table fan I could find. 3-speed oscillating cost about $10 or so.... maybe $20. If you're going to camp without electric hookups, get a 10" Endless Breeze box fan (12v). It's quiet and moves a lot of air. Only draws an amp or so on low speed. With both, the key advantage is we can put them anywhere and aren't limited to hanging from one spot on the bunk end.
