Yep, something went out on charging from running the rig engine. I just ran mine to pull out of garage, checked coach batteries and charging at 14.4. Shut off rig engine and started generator and checked batts running off genny and charging at 13.58V. I hardly ever use shore power to charge batts. I use a small trickle charger about once a month. After disconnecting trickle charger, measuring batts Voltage after 24 hr. rest, measured voltage is 12.85V. After 30 days drains down to 12.63. Clean connections etc. but there is still a trickle loss over 30 days. Guess maybe O.K. as still holding slightly above 12.6 which I read for 12 volt is 100%. Hope you get yours worked out O.K. I understand your dilemma, real PITA stuff to contend with.
