Ok that all makes sense. I also hadn't thought about effect on the 12v battery from the cold.
- When you go to drive, you can pre-condition the cabin using "shore power" rather than the battery. This will increase your range and may be more economical as their are losses inherent in charging/discharging any battery.
- Keeping the truck plugged in will help keep the 12v topped up
- PowerUps require the truck to have sufficient charge in the 12v battery. Keeping the truck plugged in will help make sure PowerUps install.
