Freezing and thawing does a number on cabins. The best cabin-maintenance requires that you keep the cabin at aconstant temperature of whatever you want (or can stand.) But if you’re off to Hawaii for winter break and don’t want to pay for the heating fuel, PREPARE FOR FREEZING!
One very important reminder if you do let a cabin freeze is to dump out all your carefully-hauled water. If it’s left in jugs to freeze, it will crack the jugs and you’ll have to haul out a 10-gallon ice cube anyway which will melt last and remind you for the rest of the winter and spring how hard it was to drive and pump and haul all that water and how you let the jug crack and water, (precious water,) go to waste!
If dumping out water is too traumatizing, the five-gallon blue jugs have enough elasticity to expand A LITTLE BIT. If you leave the cap off the jug might make it with half a tank of water without bursting. No guarantees.
