I just installed the Renogy DCC50S DC-DC solar charger for my two 100 Watt
solar panels on the roof of the van. It's great to have one relatively
small device that can charge the starter battery and house battery through
solar and/or alternator.   I have also looked into the possibility of
hooking up shore power. I believe the easiest way is to connect a battery
charger to the house battery. This would charge your house battery when
connected to shore power, but not the starter battery. That
shouldn't really be a problem as the starter battery is typically not
discharged while
camping.
