This should help with future GM EV tow vehicles.

Unfortunately doesn’t include Volkswagen’s Electrify America high speed “pumps”. But that could change by the time the EV Silverado hits the streets. Kudos to GM for addressing an important aspect of the EV transition. Most of the time people charge at home, but doing road trips with half a dozen different RFID cards and payment methods is a real PITA. Ask me how I know. :).
