As for ice keeping ability, no need for spending a couple hundred dollars on expensive coolers.
A regular cooler lined with the ridged foam insulation will keep ice for a week easily.
Even just a piece cut to fit the top under the lid will make it last much longer.
Years back we went to Quebec every year for remote wilderness type camping/fishing trips.
You took in what ever you needed for the entire trip, as It took a whole day to get in there from the hard road.
We used one large cooler for ice storage lined with foam, and others with foam just for under the lid for general use.
We always had plenty of ice left for icing the fish we took out with us after 5 or 6 days.
And after I weeded out a few serious beer drinkers, it even got better. lol
