In another thread, I posted a new observation that we made last month on Shell Island...
What weebray said with an exception....

insulate it with your sleeping bags or ????. Keep the lid closed. Know exactly what is in your cooler and where so you can quickly grab what you
need. No opening the lid and "looking around". Drain off the melted water. Never add anything warm to the cooler. Cold food and drinks are a
luxury. Consider dried foods and powdered drinks to relieve the pressure on your coldness. All drinks should be in aluminum cans. Use the
refrigerators of friends, motels, stores and strangers to your advantage. I'm sure there are other tips I've forgotten. |
The exception being about draining the melted water out.
I (and my father) always believed that removing the water helped the ice to last. In fact, if the melted water is left in, at least 50% anyway, the
remaining block melts slower. This is in a stationary condition, not driving/ sloshing.
We had identical Coleman 5-Day chests.
One had two (10#) blocks, and some frozen water bottles and some crushed ice to fill in gaps. This one was for food and some drinks.
The other had just one (10#) block and crushed ice, into which went the beer and water bottles. This one was not drained and was the one opened
frequently (to get drinks).
The food box with two blocks and some crushed was only opened at meal times very briefly and the water was drained daily.
After 4 days, over 90° days, the drink box with just one block and melted water left in, still had almost half a block remaining... and the water with
the beers in it was ice cold.
The food box, originally with 2 blocks, drained daily, rarely opened, was nearly gone of ice.
That was an eye-opener and except when driving, I won't be draining the melted water out or much unless we are driving and will be getting more ice.
(food is placed in snap-tight containers, so the melted ice shouldn't hurt)
