DC-DC Charging ?
When you add a DC-DC charger from the truck as in several threads about that, does that put the house batts in parallel with the engine batt? (as with normal "alternator charging" via 7-pin) Or is...

My 1991 C's alternator is fairly lame. They got new ones in the 1992s.
With alternator charging in the C as is, I get 30 some amps at first and then it settles around 20 amps. So no point in using a 20 amp DC-DC in mine to get more amps. Also house and engine batts are all FLA no mixing worries.
When there is solar, it has a bit more voltage than from the alternator so that cuts back amps from the alternator.
With the Renogy, I suppose I can dial the solar voltage to match more closely so they add their amps better than they do now. Haven't checked to see if the Renogy has adjustable output voltage--I think so. Then I could dial them both to 14.6 battery spec and they will add their amps better.
