You will see a really nice truck drive up for an award on a video.(Black with red roof) Here is my question what is the round cylinder on the passerger side window? I've been asking some guys I know and everyone has no clue. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | early air conditioning, an evaporative cooler

The effect is cool. I paid $10. for it about 18 years ago.Try and find one now, good luck.They are how ever cumbersome and ugly, not for every one.They are a period item tho!!!lol

Scott Because when the water starts to green up, it smells like a swamp?

Joined: May 2005 Posts: 8,878 | It's an evaporative cooling "system" perhaps "swamp" because it's wet, or because it's simple/primitive? A family member had one to cool his store, and another family member had a big one for a movie theater. From: http://en.wikipedia.org/wiki/Evaporative_cooler"small-scale evaporative coolers are called swamp coolers by some users due to the humid air conditions produced."
