What good is a battery disconnect that still allows parasitic draws???
I know the disconnect does not impact the radio on mine, it continues to run and I have to hold the power button down to turn it all the way off. But I suspect the radio runs of the Ford battery instead of the house?
My stairs also continue to deploy after the switch is thrown, I am not sure about the LP sensor? Is there any chance the stairs are run off the Ford battery as part of the safety feature which causes them to retract once the vehicle is running?
As a shiftworker it is not unusual for me to go 3-4 weeks between trips so even small draws like the propane sensor are enough to significantly deplete the battery. If these things do continue to draw I will have to consider adding a secondary disconnect to properly protect the battery
