I experience the same problem of dead batteries when the coach is parked for 15 or so days; even when connected to 50 amp service. I thought that when connected both the house and chassis batteries were being charged. On this most recent occasion I was told that only the house batteries are charged, not the chassis batteries. I have a 2008 Monaco Diplomat. Is there any modification/addition that can be made to also charge the chassis batteries when connected to shore power?
