   I started the earlier mention of using a cooler.   Olddawgsrule is correct --insulation is the key.
I said that we used a quality cooler-it is an Engel , but the best part is that I made an insulated cover for it. I used REflectix roll insulation

which is available at Lowe's. It is 1/4" bubble wrap that is faced with reflective foil.  I used three thickness of the wrap.  Lowe's also has a special foil tape for joints at the seams.  The top can be taken off and leave the bottom in place. 
We have kept ice as long as 9 days-we freeze it in gallon jugs and put i jug at each end. Makes good cold drinking water also.

hope this helps

	A couple years ago we bought a Lifetime 55 quart ice chest to take on a trip to AZ anticipating boondocking for most of the trip. Though we didn't really boondock as much as we anticipated due to our friends' camping preferences, I really appreciated the cooler. I have put drinks and ice blocks in it and it keeps everything nice and cold for a surprisingly long time. I usually fill big Costco plastic jars, like for nuts, with water and freeze it. I've had that ice stick around for as long as a week. The ices chest performs every bit as well as the high priced brands that cost over $200 or $300. Here's a link I found for it today. https://sunnypetra.com/index.php/lifetime-55-quart-high-performance-cooler-grey.html?utm_campaign=gs-2019-07-05&utm_source=google&utm_medium=smart_campaign Lifetime products, if I'm not mistaken, are made in Utah, which I think is still part of the USA.

	If you want to add insulation to a cooler or refrigerator then its best to use a high r value foam insulation material like polyurethane and make it as thick as you have space for. The Reflectix type materials' insulation values are highly overrated for this kind of application because they depend on reducing radiation losses across a dead air cavity like an attic space. You don't have a cavity like that in a fridge or a cooler. So Reflectix foam is only about R 3 per inch and its about 1/3 inch thick so around R 3 for three wraps. Closed cell urethane is about R 6 per inch so a 2 inch space would give you R 12. To get that you can buy a cooler which already has 2 inches or more of foam in it. Ignore the fancy brand name, look for the foam, and don't forget to check that the lid also contains foam. Or, here's a DIY way to do it : https://www.youtube.com/watch?v=zC7UcJZFZvk When it comes to insulation, like they say in the automotive world, there ain't no substitute for cubic inches.
