On a Sunseeker like yours, the tank heaters will not keep the water pump, water filter, and associated plumbing warm, nor will the tank heaters keep any water in the fresh water tank or water heater from freezing. The pump and filter are in a basement bay typically heated by a furnace duct. If you store indoors, you can't (shouldn't) run the furnace.
The tank heaters also may or may not heat enough to keep the waste drain valves from freezing in really cold weather.
I store indoors in unheated space, but with power available. If I want to just keep things from freezing for a short while in relatively mild freezing weather, I run a small thermostat controlled 300 watt heater in the water pump bay, and a larger space heater in the living quarters, along with the waste tank heaters (but only if there is liquid in the waste tanks).
My climate is like yours, since per your profile, I probably live within 30 miles of you.
