Bill,
I've seen a battery combiner once.
Basically, to me it looked like a big starter-type
solenoid/relay that connects two batteries.
If memory serves me right, the solenoid is activated
by sensing a voltage increase.
It wouldn't be that different than using a 50 amp relay
with a larger trigger wire to the Bosch alt.
It would make installation easier, if one wouldn't have
the relay trigger circuit like in the vanagon.
But you can't really compare it to an isolator.
Btw, Sure Power isolators are used in lots of marine
applications.
Have fun.
