Iceless coolers for food

The ice-less coolers generally get about 25-35 below the temperature of your cab, so unless you normally like it real cold, 40 is pushing it in the summer(https://en.wikipedia.org/wiki/Thermoelectric_cooling.) I have found out the hard way(several times) that it will not keep mayonnaise from spoiling(about 3-4 days max,) it might just be my cooler not getting that cold.

Yes, they have ice. Let us know how it works out for you. I'm just way too lazy to stop once every 2 days to restock(that's during the winter, at least once a day during the summer when I was running ice way back...)

 

Do you have an inverter?

 

I hadn't seen those, nice find. Another plus to having an inverter is that that will have put a large hole in the floor to run the power cables and you could use that to run your drain.

 

Like 2.50 a bag of ice. I use to have an ice cooler but the ice and draining it was a hassle. I have a kooltron and it's been going strong for over 2 years. As long as I keep the temperature in the cab cool, my food stay around 30. In the winter, my water will half way freeze

 

I am using a 20 year old koolatron, it has outlasted 2 colemans. The motors keep getting noisy in the colemans, I've never had to replace anything in the koolatron.

 

Be sure to clean your cooler often, and the hose you're going to build as well. It doesn't take much to spawn a mold spore and then everything is compromised till a good steam bleach Godzilla fire cleaning. Depending if your hose is always in the dark and its a good temperature, you'll have mold sitting in it within a few days after the first use.

Now onto cold business,

I had a 40 can or 40 qt Coleman iceless that worked pretty well. It works off ambient temperature and gets the inside cooler temp 40° below the outside temp. And stopping at around 25°
So if the truck cab was 80° the inside of the cooler was 40°.

I put mine near an ac vent to trip the thermometer and when I was out of the truck with the ac off, I put the cooler as low as it could go on the floor.

I never had any issues with mine, ran it hard for about 8 months and always had future meals and drinks in it. Home time, id either take it home and clean it or unplug it and leave it in the truck.

Some people have said their plugs burned up on the Coleman, mine never did. Watched it constantly, It did get hot to where I was worried but it never burned up.

 

The only thing that broke on my kooltron, was the 12v plug. Students kept stepping on it until it broke. I had big fellow about 350 lbs using it as a step stool to get on the top bunk. Not even a crack on the body. The 12v replacement was only a few bucks.
