[VAC] A/C, swamp cooler and/or fan recommendations to replace carnk-up vent?

Wayne: I have done both install a Fantastic Fan and a Penguin Dometic 
a/c. Both work great without putting in additional holes (caveat: the 
dometic drains condensation; either drain to a nearby external vent pipe 
or bring through a tube for inside drainage to a vent pipe. Otherwise 
water runs down the outside of your a/s). Your decision will be based on 
1. cost: a/c is $500-1500 depending on who does the installation.  
Fantastic Fan is cheap-$200 and easily installed by anyone. 2.Your 
weather: If its hot and humid alot, and you have the $, go the a/c. 
Otherwise do the Fantastic.
