Loren,
    Personally, I would add a relay that connects the aux battery (to the
alternator)only  when the car is running. Otherwise you run the danger of
discharging both batteries.
    I would not use steering diodes due to the loss of precious electrons.
    When in camping mode, I am too lazy/forgetful to use a marine battery
selector.
