    I was actually thinking that I can make an even awesomer cooler with a couple plastic totes and spray foam.
    Sticky!... Much!

    It helped but it still sucks compared to my Yeti. It will keep ice throughout the day and I don't have to worry about anyone steeling the ugly POS.
    A length of chain and a couple of (hardened) padlocks (and a handy tree, in camp) secures my Pelican pretty well... just to keep the honest folks honest...

    Enjoy!

    Tents work best for me, so far.
    Experience along with properly set up 4WD will get you to & through places (on existing, approved 4WD trails) that 4WD, alone, can't get to.

    I recently experimented with a small lunch box type cooler. I drilled a hole in opposite corners of the lid and then sprayed foam in one hole until it started coming out the other hole. I made a horrible mess! The foam expanded, and expanded, and expanded, until I had a huge blob of sticky goo coming out of both holes. The lid did not deform but after the foam dried I held the lid up to a strong light and found the foam did not fill the entire lid, in fact, I think more vented out than stayed in. I think now I would drill more holes and squirt in a small amount of foam, let it expand, then squirt more foam into open holes. I would do it gradually until I had the entire lid full.

    As Happy Joe said, it is STICKY!! This is not a project you want to do inside your house.

    "Reflectix"--I had also covered the outside as well as the inside of my cooler with "Reflectix", and have used it for the last 3 years. Pictures below. I made a complete cover to go over the cooler. Leaving 3/4 inch short from touching the ground. (Also used the foil tape) Cut slots in the ends, to reach in for the handles. For the inside of the cooler. I used "Reflectix" also. 3 separate pieces. First made a double bottom. Then made the the sides in one round strip. Creased it where the corners were and slid it down to meet the bottom. Made a floating top piece double thick, like the bottom. It doesn't take up hardly any room. For ice I reused 64oz fruit juice bottles that fit nice in the corners and 17oz slim bottles with salt water in them. See picture. Salt in the water is the key for longer lasting ice. The bottles need several days to freeze hard. Leaving 2-21/2 inch. space at the top for expansion. The slim bottle go on top of food and between food, if there is a gap. I can get three to four good days of good ice sometime a little more. Depending how offers I get into the cooler.
    Hope this might help someone.

    Pics didn't come through....but I lined the inside of the cooler and use gatorade bottles filled with salt water too. Then I dump ice cubes in to fill in the voids. A row of bottles on the bottom ALWAYS keep the food from sitting in water but the last time I went camping I used about a half bag of ice and when I came back 3 days later had about a half bag of ice left.

    The salt water melts faster but freezes colder so it retains the cold longer than water. And since it is in bottles doesn't make a mess in your cooler. The problem I have had is that my food actually freezes. I put a carton of Egg Beaters in the cooler right before I left on Friday. When I went to use them on Saturday morning I found it was frozen. So you have to be aware that thawing may be needed.
    I would feel more optimistic about a bright future for man if he spent less time proving that he can outwit Nature and more time tasting her sweetness and respecting her seniority.

    James, Thanks for your reply. I just sent a questionnaire to the Webmaster on why the pictures didn't Post with what I wrote on our subject of "Insulating Coolers". Waiting to hear back. To your question, about other food freezing from the saltwater bottles. Food products that I eather prefreeze or don't mind if they freeze, like meat for example. I place the square fruit juice bottles that fit in corners better at one end and pack the meat around it. I will use them in a few days, because of my meal planing. But other foods that I don't want frozen. I have put one or two pices of the Reflectix, between the bottle and the food. And it helped. With the bottle in the corner. The Reflectix should be covering one side and one end. But make them a litte longer so they can flair out a little. The prices should come up a little higher then the top of the bottle. If need be. You could even put a piece of the Reflectix on the top to isolate it even further. You will have to experiment, to see what will work for your food and cooler. I am posting the pictures again. They might work this time. Have a good day James!
