Keith, I have 4 of the AO coolers, I don't think you will be able to get much bigger than the 36 can cooler in the table with ice. I have both the 36 and 48 can and they get big with ice. I'm not sure what the hard coolers get for time for things to stay cold, but my AO coolers will get 3 days out of them. Another plus with the AO over hard coolers you don't have to worry about them sliding or scratching inside of boat when you are cracking the whip(tube) with the kids on back!!!! Much easier to carry too!!
