My 2005 Monaco Executive DP chassis batteries go dead in dry storage. Yes, I understand why: the built-in "battery disconnect" switch doesn't (by design) actually disconnect everything. (Contemptible switch labelling, IMHO.) Yanking the negative cable kills all parasites, and that's what I'd like to do, but I don't know what headaches to expect when I reconnect. I've heard I'll suffer rough engine and rough shifting while the control modules re-learn, but I don't know how bad that is or how long it takes. And I wonder what other systems will require manual reconfiguration (or re-learning) after complete powerlessness.
I've considered adding a solar maintainer, but can't guess what wattage is enough to offset the not-really-disconnected parasites.
Your horror stories or reassurances would be most appreciated.
What's the downside of chassis battery disconnect?
