are the batteries going dead while sitting
or do you mean , they go dead while you are driving, and the only thing keeping the engine running is the alternator, and there is no battery power for restart
they should not die that fast unless there is a short circuit someplace
1980 has a electronic voltage regulator near the fire wall or mounted on a stanchion at the back of the engine under the dog house
measure the voltage at the batteries with the engine running, then at the alternator
i suspect the 'diode based' battery isolator is the culprit and has burned out
you can get a new one at pep boys, or camping world
the isolater will be mounted up front under the hatch
or
near the engine battery if its some place like under the steps
one other thought
does your kings highway have a large knob/switch near the floor of the drivers seat, labled main aux both off
be sure to place on both when starting and driving
that is a 'marine' battery selector switch
