My wife and I have an unexpected week off together next week where we are dropping off one of our kids at camp in one state and picking up the other one in another state a week later. We are going to be travelling through Florida so I decided to try to book a room or condo at the beach last minute but there wasn't anything available that wasn't prohibitively expensive. I pitched the idea of camping on the beach to my wife and bless her heart she agreed! We have a small 2-3 man tent we got for the kids last Christmas. The campsite is at a Florida State Park and it has power, water and and an air-conditioned shower and bathroom facility but I became a little concerned we would be rolling around in our own sweat every night in that little tent in hot, humid Florida. I briefly investigated purchasing an indoor or portable AC unit but they are much more expensive than regular window units and frankly I don't think we have room in the tent for one. I read with great interest this instructable by zmatt (Thanks Matt!) so I did a little research and found this cheap, little GE window air conditoner that gets rave reviews at my local Wal-Mart for $98. The only problem is that since it is a window unit, it is not designed to be carried around so the aluminum fins of the condenser unit on the back are exposed and can be easily bent or damaged during transport. I came up with a cheap solution to protect the fins and ruggedize our new little camping air conditioner.
UPDATE: We just got back from our trip and the air conditioner worked even better than I thought it would. The first night my wife asked me to turn it down because it was a "tad chilly". lol We were nestled in our sleeping bags too! Not too many bugs showed up but the laundry bag saved the air conditioner one day when a monsoon passed through the campground and the water pooled at the condenser end. So much so that the fan blades were slapping the water and I was thinking "Oh no! It is splashing dirt and debris all over the inside of the air conditioner!" but after the rain I took the bag off and it had kept all the dirt and debris out of the air conditioner. The door of the tent didn't zip snug against the side of the air conditioner so there was a little wedge of daylight there so I stuck a little soft cooler in the crack to seal it. OK, gotta go add a 5-star review for this air conditioner at walmart.com! Best money I ever spent!
