2021 Jeep Wrangler Unlimited 4xe Flat Tow Set Up

Question:

The new Jeep Hybrid 4xE does not have an alternator, but instead uses a fairly complicated dual charging system module. I wish to flat tow this vehicle behind my RV so that the bus provides power to the turn and brake lights as well as charge amperage to the vehicle itself. 1 Does the appropriate wiring harness exist yet, and 2 will this harness allow for the 7-pin? to charge the main batteries in the jeep?
