Let the cooler be the ice saver don't try to make the ice be the cooler saver.
Before we purchased our TT we were tent campers and I always fought the ice battle trying to figure out how I could have ice last 4-5 days to keep the food and more importantly the beer cold.
I tried dry ice, ice packs, thermafreeze, techni ice, and good old ice packs.
What I found is first getting a well insulated cooler (i used and still use the coleman 6 day coolers that are stupid thick with insulation) will trump any fancy ice system. Making sure the seal on the cooler is solid and its not constantly being opened is the key.
My personal favorite was thermafreeze, they lasted as long as thick ice packs but were easier to move around in a cooler, as such I got 5-6 sheets in a cooler and that made it really cold and long lasting. The only downside is they absorb water till they burst so they cannot be mixed with regular ice or something that might melt. I found I had/have great success with taking 2 2L milk jugs and freezing them solid a week before the trip. Because the block was thick the density allowed it to stay frozen longer and the jugs prevented any water from leaking out.
