If you read the instructions and/or research on any of these high price coolers you discover the advertised amount of time it will keep ice is if you precool the ice chest, fill it with chilled products, top it off with ice, then never open it again
I have a Yeti (given to me), and when doing the above, it does perform as advertised. But if you are using it as a beverage cooler and opening/closing it often, it performs exactly the same as my 20 year old cheap Igloo cooler.
So when boondocking for weeks, we do like the outfitters and put frozen food and ice in the Yeti as described, then don't open it for a week. We use my old reliable Igloo for beer and sodas. Perfect
