We have lived aboard in Mississauga, Ontario for eleven years, when it gets cold we turn up the heat
We shrink wrap the boat and that makes a big difference, we run hoses under water and to fill our tank we haul the hose up to the club house and feed water from there. Keeping the hose under water keeps it from freezing. We also have portable pumpout dolly.
the only time we get claustrophobic is when we stay ashore at one of our kids places for a weekend.
Dirt people scare me.
