Battery Charging Problem ***UPDATE***
While dry camping in freezing weather, the charging system died for the dual type 24 house batteries (2002 Winnebago Mini). It appears to be a solenoid system. It failed two years ago and the RV s...

That is why a DC to DC voltage boosting device works better. You will still need a solenoid so that the starter battery is isolated from the house batteries when the engine is not running.
I have NEVER seen a DC-DC charger that will allow the house battery bank to send power back to the chassis battery without some kind of "bypass" being applied.
(FYI - A DC-DC charger actually first converts the incoming DC voltage to AC, runs it into a transformer (or some kind of inductor). The resultant AC is then converted back into DC. Current can not flow "backward" because DC current can not flow through a transformer/inductor.)
dc to DC is one way. But we don't want it to draw on the starter battery when the vehicle is not running. Therefore an isolation device needs to be used.
