In my opinion coolers are all about the application. Many guys don't match their cooler size and specs to properly meet what they are trying to do with them. Another issue is dealing with hot temps when we hunt in California and Arizona.
Also, unless you are simply keeping drinks cold for a one or two day barbecue, stop buying bags of ice. You are throwing away money and this is the quickest way to get frozen water to melt (crush up the ice and space it out in a cooler). The countless "cooler comparison videos" where some random guy (wearing sunglasses is mandatory btw) dumps bags of ice into different coolers and throws them outside makes me die a little inside haha. I can't believe people actually watch those videos and make buying decisions based on them.
I have used just about every cooler out there these days. Most of them do a great job if properly loaded, properly iced, and not opened and closed all the time. A dedicated ice cooler is a must if you're planning on hauling out lots of meat and keeping it cool for long periods of time.
At the truck/trailer or base camp, we keep a Pelican Elite 250 or 150 depending on group size, filled to the brim with frozen 1 gallon water jugs. As an example, the 250 can hold over 30 frozen 1 gallon jugs. This cooler never gets opened unless we show up back at the camp or truck with an animal and need to take some jugs out and move them to one of the meat coolers. We don't like to use the milk jugs, they are thinner plastic and an odd shape. The rectangular water jugs with the thicker plastic work much better. This cooler is purely for storing ice and moving ice to smaller coolers to keep animals cold until we get home to butcher.
The smaller coolers are chosen based on size of the animals we are hunting, and limiting empty airspace inside. Anywhere from a 50 quart to a 150 quart depending on how long the trip is, and what size animals we are hunting... We move the ice blocks into the appropriate cooler and put the meat on top, shut the lid and don't touch it until it gets home.
I am not endorsed by any companies but I have switched to using the Pelican Elite line of coolers for just about everything now. Their ice retention with frozen jugs is ridiculous. Lifetime warranty, awesome latches from their gun cases, true freezer grade seals, amazing heavy duty handles, molded in tie down points, bear proof... Tested this shit out this, this July on a family camping trip. We had black bears coming into our camp site in Lake Tahoe every single night for 10 nights. We ended up ratchet strapping the cooler down to keep them from trying to push it into the woods to work on away from the camp site haha. Cooler and latches are just fine.
I should do my own stupid ice retention test with my Elite 250 loaded up with frozen 1 gallon jugs. I've gone 2 and half weeks with 12, 1-gallon jugs and a ton of camping food, getting in and out of it multiple times a day. The jugs were still at least half ice and half water at the end of that trip. That was 85-88 degrees during the day and 53-55 overnight lows in July this past Summer. It would be fun to load the 250 up with 32 frozen 1 gallon jugs, shut the lid, and open it one week at a time and see how long it goes. Maybe I'll give this a go at home this late spring when it starts creeping into the 90's.
