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...

DC to DC converter should be a "one way" device but to ensure it is..
Insert a Schottky Diode in front of the DC to DC converter to ensure your vehicle battery and charging system are not going to damage your house batteries.

"Low Forward Voltage Drop
One of the chief characteristics Schottky diodes are known for are their low forward voltage drops.
Their low forward voltage drops means that they consume less voltage than a typical diode.
A typical silicon diode consumes about 0.7V across its junction.
A typical schottky diode may consume only 0.3-0.4V across its junctions. Thus, it saves about 300mV of power. "

Those actually are a "dual diode" package, contains two diodes that you can parallel if you like..
