Sean B:
        Thanks for your reply, but I still have a couple of questions.
        Are you saying that only those electrical items specifically wired
or rewired to the new aux battery can be run off of it while
camping?  Then the aux battery is "isolated while driving?".
        I would think the best arrangement would be for the usually in
cabin electrical items (sink pump, overhead light, dash radio) and added
things like aux heater would be run off the aux battery via the standard
wiring while camping, and that the starter battery would be
"isolated".  One could then listen to the whole red sox division series,
wash dishes, read by overhead lamp, all while camping, without risk of
having an inadequate starter charge when it was time to drive away.
        Most everything that I want to use while parked is already wired
to the starter battery.
        Does this make sense?
