I have a 2016 GMC Duramax. GM tech told me everything electrical goes into sleep mode on this truck when it is shut down for a period of time, just like a laptop. I have had no problems at all with 2 month shut down. I pull camper hotwire fuse under hood and do not set alarm, just manually lock doors, then turn off camper batteries main power switch. No current draw anywhere. ......wonder if OP pulled camper charge wire fuse?...
