Well just checked the ice. Had to dig 20"s of snow off and we still have 15"s of ice under there. Good ice too no grey soft or slush spots. It is good solid ice the black kind.
The mopar started right up in this cold even faced into the wind. We had a record broke here of -26.5C and with the 50Km wind it was -45C and the dodge started right up with out being pluged in. Good battery is a life line in this cold.
