You normally get RV antifreeze that is usually rated for -50 degrees, but up here in Canada and probably Alaska, you can get Antifreeze rated for -100 degrees. This means that if you are looking to dilute the water in the waste tanks to lower the risk of them freezing, getting -100 antifreeze would mean you only need to add half the amount vs regular Antifreeze. This would mean carrying half the amount of jugs with you. However you may find the cost to be more than twice as much. Camco 30787 is the p/n for one of them, however it is Glycol not Ethanol, so it costs way more but does not leave a bad taste in your fresh water pipes.
