I have a like new (only used for 2 weeks)20k BTU window unit A/C that is explosion proof. These units are normally used in the offshore oil industry and new cost is about $3750. I am asking $500. Drastic Price drop These things are extremely heavy duty and will last a lifetime in the hunting camp. i am always interested in trading for guns,ammo or most anything outdoors related. If you are wanting to trade some ammo or guns then do not attempt to trade your hyper inflated priced items unless you make it worth it in real terms. This is equivalent to a 2 1/4 ton unit and able to cool a large camp. 985-859-6422 or 6402
