2020 3500HD power port problem
I just recently got a 2020 Silverado 3500HD, and I've started a never-ending cycle of charging a dead battery. This is caused by having a CB radio, GPS, and dashcam plugged into the power port. The power port doesn't shut off when I turn off the truck so if I leave the truck for more than 2 days, the battery is too low to start the truck. Thanks to Covid, I work at home and the truck will sit in the driveway for up to 5 days. Is there any way to get the power port to shut off? If not, where can I tap in to power and ground lines to power these devices? TIA

connect them to a Retained Accessory Power (RAP) circuit. It will shut off automatically along with radio, windows etc.
