I think the winter hit will be much less fun that this truck. Almost minimal if you utilize the seat heaters rather than cabin heat. Even in my golf the heater/winter hit is around 25%. Given the miles per kWh on the F 150, having a 6-8kW heater running will use up less range. If this truck gets 2.5 mpkWh then you’d lose less than 10 miles of range per hour the heater is on. Depending on the thermal management the cells will hold less energy than in optimal temps. No way this thing only goes 50% epa in the winter.300 miles is minimum. Plan for 50% usable range, during winter, even without towing.
