A month into my new 2026 SEL and looking at things to do this summer. We've enjoyed the Mahoning Drive-In in the past and, based on my understanding of accessory mode vs keeping the car fully on when parked, the best bet would just be to keep the main system on the whole time to avoid discharging the 12V. Am I on the right track? Should I just turn it all the way off and bring a battery radio (like you're supposed to do with an ICE to avoid choking everyone)? Run accessory mode but start the main system periodically to recharge the 12V?

Does anyone have any direct experience with a similar usage?

EDIT: Aha, UTILITY Mode. Thanks all!
