That's the big question and the odd fact why would the battery boil over some yet still show dead upon arrival. It's going from overcharging to running off the battery so much it's dead upon arrival. I shut off the same things ever time AC & Radio. Hookup is the same. I'm trying to find out when in Tow Mode what is actually stil on. The lights run off the coach only the RVi Brake 3 is off the car's 12V/Battery. Though I've been thinking that if I disconnect the so-called 12V to the relay from the MH and eliminate the battery from the equation then use that 12V line from the coach to run the Brake system there should not be much draw other than what the car has on when in tow mode.
I suspect the adaptive steering and several other things stay on throughout the towing ordeal.
Thoughts, anyone, on this approach?
