Thanks for the test OP, great info. I am always somehow drawn to cooler ice test!
I started camping/hunting on my friends property about three years ago. It is 2 hours away and has no running water or electricity. We stay the week of July 4th and about 3 other weeks throughout the hunting season and about 3-4 weekends through the year. What I have learned is this.
#1 Have a big cooler for food, and a smaller cooler for drinks. Pack them full. The food cooler only gets opened a few times a day and the drink cooler is OK if most of the drinks are floating by day 3 as long as they are still cold.
#2 Make block ice. I have 9x13 cake sheet pans for the big coolers, and I have small loaf pans 5x9 for the smaller coolers. Two weeks before the trip, I start making the blocks in my garage chest freezer.
#3 Keep them covered from direct sunlight.
I would love to see this test done with block ice filled 1/2, maybe with only 4 coolers since you would have to make the blocks.
This is the
cooler I use, I always have wanted the high end coolers, but $30 is hard to beat for the camping that I do. When the technology comes out when they can make a Yeti that is as light as the Coleman, but performs 25% better then I will be first in line.
