Thanks for the info. Sounds like you have a good base camp.

When we camp in the cold below 20-F we try to leave one door open on the kitchen and bathroom cabinets. But using water it drains to the gray tank, which will freeze.

Try removing the aerator on the kitchen faucet. Years ago, we had an issue when we connected to city water. Starting with an empty hotwater tank. We stirred up the settlement in the water heater and it caused the aerator to clog with no water flow.
