Notice in the video when he cuts the hole in the lid of the Coleman Polylite 34 qt cooler that there's absolutely no insulation in the lid, just hollow space. The same for the follow-on video made with the Island Breeze cooler. This doesn't matter for the air coolers they're making, but pay attention when buy a cooler to go camping. Let the sun hit the lit and the heat will go right on through to inside.
Now all you need is an easy/cheap way to make a lot of ice while sitting out in the middle of Quarzsite......
Other than that, it is pretty neat. You even put A/C under the MH or TT when doing some work on it.
