I'm considering picking one up for myself, and possibly another as a gift for family.
What size is ideal? I've seen some ranging from approx 25 qts, 50qts, 60qts, 75qts, and even larger. I know "ideal" will differ based on individual usage, but perhaps for something more general purpose such as a day trip to the beach/river, a weekend camping, etc.
If it's a larger size that is recommended, would I be better off with for example 2x 25qts instead?
TIA.
