I can't afford an ARB fridge so I came up with this.
I have a Pelican cooler that I really like. Holds the temps really well. So I took that and put a smaller cooler inside it and I fill that with dry ice. A small cooler like this will hold about 10# of dry ice in chunks. I pay $15 for 10# of dry ice. With that little cooler shut it keeps temps down to about 33-37 degrees. Open it will drop the temps down to single digits. I line the little cooler with cardboard to protect it from damage. Also the little cooler will keep the dry ice for 4 days but the temps will stay cool for an additional day. Oh and I also put a little battery powered RV fridge fan in to circulate temps but you can leave that out if you want to place frozen foods on the bottom as cold air sinks.
It may seem like it takes a lot of room but it takes up less room than a bag of ice. Also the little cooler can be used as a shelf. I put our frozen food and drinking ice around it in direct contact and those items stay frozen solid. Also this keep everything dry and makes it a lot easier to find items, there's no need to dig through the ice.
One note because the dry ice off gasses CO2 you need to make sure the cooler is vented. So high quality coolers like Pelican,Yeti,Orca etc.. need to have their vents opened a little to let the pressure out.
