Most newer RVs will charge the house and chassis batteries when a charging voltage (+13.7) volts is detected. You didn't mention what year your RV is, so I can't do the research for you. I'd take voltage readings of all batteries, then plug into shore power. Take voltages again. If you don't see an increase in voltage, then you know the converter/charger isn't connected or working. It might just be a tripped breaker on the converter/charger box. You could also look online for your make/model of C/C and find a manual for it. If you find an increase in the house battery but not the chassis battery, it either indicates your battery isolation relay isn't working or you don't have one.
Do you have a 'boost' switch on the dashboard or under the edge of the dash? That would indicate you have a relay that connects chassis and house batteries. The relays are often in a box under the hood with chassis fuses and relays.
If you go to the tab 'User CP', on the left side you'll see an option to 'Edit Signature'. There you can add details about you, your RV, or anything else you want to have appear in each of your posts.
