Hello New to the Forum. I have I believe a unique situation and was hoping that someone may have had the same. For the last 2 years I have noticed that when I disconnect my RV from the truck and it sits for a couple of days the battery will drain not starting the truck. 2 different RV's, new 7 pin and brake controller. Also dealer could not duplicate with out RV. Obviously a drain after the RV is disconnected. The crazy thing is after using (with RV disconnected) when jumped etc the truck after disconnected I can leave the truck parked for days etc and it will start? Obviously again something is staying on after the RV is disconnected then shuts off eventually. I found a discussion where supposedly their is 4 relays under the Power Distribution center for the tow circuit but it is a little confusing as it seems that may not be plug in's . Of course on the PDC there are fuses for the tow circuit. The schmatic also showed the Module Body Control in the circuit? I assume this is the connector? Anyway with not being able to find the drain will a battery disconnect work? And if so what should I use? Thank you
