The harness does not automatically charge. A separate charge cable is needed. There are several mentioned in this thread. Be sure to get one that has a automatic controller so when motorhome is shut down the controller will not allow feedback to the coach and drain the jeeps battery.Noob question for you in the know. I had the mopar flat tow harness installed along w tow harness. We just arrived in San Antonio and disconnected Moabee and battery was dead. Isn’t the harness supposed to keep the battery charged or at least use RV power for the lights? Not sure if I’m missing something or amiss.
Was only connected since Friday, today is Sunday.
